XCOM (most enjoyed Enemy Within, with Long War, other versions also generally good), just a masterpiece.

Into the Breach, probably the cleanest, and a great theme.

Lots of deck-ish based battlers: Slay the Spire (1 and 2), Backpack Hero, Monster Train

The Last Spell, Battle Brothers

Lots of D&D or adjacent stuff that board/tabletop-like: Balder's Gate 3, Gloomhaven/Frosthaven.

Edit: Wasteland series and Shadowrun series also great.

I generally prefer turn based, so no specific game

Baldur's Gate 3 and Expedition 33

First one is a great game, but combat is not the most important feature of the game IMHO.

The other is very good, and the combat is more relevant.

I think that the engagement is being able to build a strategy on how to win, instead of rely more on reaction.

Baldur's Gate 3.

I normally hate turn-based games with a passion, but they way they handled it is amazing. Combat is visceral, brutal, and rewards the player for spending time to think before they act. You can do some really crazy stuff if you think outside the box prism.

Advance wars on the gameboy advance. When I was in the navy weʻd do the turn based 4 person mode with fog of war, and just hand it around the ship or when we were on leave.

Chrono Trigger comes to mind

I grew up playing the Final Fantasy series starting on the NES. I recently got FF7 remake on steam sale and have been putting time into that, but they did change it from turn based. I think at least FF1 - 11 are solid turn based games. Don't think I played any after 11

Brogue, Hoplite, Stone Soup and other roguelikes

Final Fantasy Tactics Advance

Battle for Wesnoth

Heroes of Might and Magic

various card games

basically, any game with significant tactical depth can benefit from well-done turn-based timing

Worms. Literally any Worms title.

Additionally: Transistor

Advance Wars 1 and 2, absolute bangers

Masters of Orion 2

XCOM series and similar turn based tactical games like Xenonauts 2 and Phoenix Point (most recently Star Wars Zero Company)

Age of Wonders 3

City of Gangsters

Fights in Tight Spaces

Phantom Brigade

Jagged Alliance 1 through 3 (but not Back in Action)

Shadowrun Returns and Dragonfall

Chess

Very rarely. Pokémon and Expedition 33 are the only ones that come to mind outside of more casual games like Super Auto Pets or Balatro

Baldur's Gate 3

Divinity: Original Sin 2

For the King 2

chess

Hell yes. Final Fantasy 6. Fallout 1 & 2. Just a couple off the top of my head. This question is weird.

I generally enjoy turn based. I like casual stuff I can be interrupted while playing and not be fucked. All the way back to final fantasy.

But my favorite, bar none, is bg3. The immersion level is high for me, the overall gameplay is top end, and the whole d&d world ties the knot

Turn based is almost exclusively what I enjoy. I don't need high octane action. I prefer to drink my coffee and solve the combat puzzle

For the king 2 has great turn based combat imo

Caves of Qud

Deltarune mixes traditional JRPG turn-based combat with bullet hell action, which is fun. I also like the rock-paper-scissors system from In Stars and Time and Omori, but encounters in those games tend to become repetitive quickly.

Transistor has an interesting real-time/turn based combat system. You move around in real time, the set your attacks and movement for the attack phase, then back to realtime controls again while the meter for your next turn charges up.

Not to mention the depth of weapon combinations you can put together; it's one of my favorite games. Might be time for another playthrough.

Slay the Spire 2. You start from being able to deal 6 damage per card and scale your way up to crazy numbers, each play gets you to choose different playstyles based on what cards you get and pick.

Persona 5

Expedition 33

Many deckbuilder roguelikes I've played (chrono ark, lost branch of legends, slay the spire, ...) but that might not be what you meant

monmusu quest paradox rpg (warning extremely nsfw)

Ok i was gonna spoiler the last one for mild comedic effect but i forgot how to spoiler tag on here and gave up

Dragon Quest series is roundly awesome

Divinity: Original Sin 2. Combat system isn't perfect (my main criticism is that you can unchain your characters to set your party members up in advantageous positions and then trigger combat, which feels cheaty) but it has some cool mechanics. A lot of elemental interactions, interactions with and creation of different surfaces, factoring in high ground for an advantage, etc. I know BG3 is highly acclaimed also by Larian but I haven't played it so can't attest to that combat system.

I'm not usually a fan of turn based combat, but some games that stuck with me from the design point were Mechabellum (if that counts as turn based? It is a (really cool) autobattler), and Into The Breach.

Mechabellum is such a fun game to learn and figure out, and then you watch the battle unfold while thinking about the next steps.

Into The Breach because it tells you what will exactly happen, so it's more of a puzzle - you don't have to learn the enemy to know what they can do, and can just play it reactively. And that's a cool twist. Perspnally not a fan of gating strategy behing a wall of knowledge (i.e TCGs, or Pokemon - if you don't know the enemy cards/moves, you're basically playing blind).

Tiiiiime ago:
Vandal Hearts
and later:
Battle for Wesnoth
I don't play videogames anymore, but the last is an opensource absolute gem, still developed and continuously improved.

wizardry on the apple II

With the exception of MMOs, I very nearly play exclusively turn-based games.

The Xcom is the obvious answer, but also a big fan of the card games Slay the Spire/Monster Train. I've loved all of the older final fantasy games but found the action based newer ones like 15 grating.

Hogs of War

Most of the time, I hate turn based combat. For instance Xcom 2 was not fun for me. I really enjoyed playing Dungeon Crawl Stone Soup though.

Into the Breach

Right now, I guess Pokémon counts?

I used to enjoy an Angry Birds spin-off called “Epic”, that was one of the better ones.

Fire Emblem series is one of my fav turn based tactics games. Other ones I've really enjoyed are Advance Wars/Wargroove, XCOM, Shadowrun, Wasteland series.

I prefer it personally. I'm not a fan of games where combat is decided by reaction times and is high energy. I prefer to use proper preparation and strategy to win fights. And turn based is best for that. I'm also not a fan of "dice roll" style game mechanics for the same reason. Like Fallout New Vegas's speech system > Fallout 3's speech system. Because its based on a set skillcheck instead of a dice roll adjusted by your skill.

Yes, I’m a huge Final Fantasy fan and turn-based is what I started out with when I first started gaming. My favorite FF game (and video game of all time) is Final Fantasy X, and I remember playing late one night and falling asleep mid-boss battle. Waking up two hours later for the boss patiently waiting for me to kill it was quite nice, ngl.

Also Clair Obscur. I didn’t shut up about that game all last year. It’s just so good, especially for those who prioritize story in video games!

Grandia and Grandia 2. Atlantica Online.

Divinity Original Sin. Old 80s RPGs

X-COM. CRPGs. Pathfinder, BG. Have Ledgerbound and the new FF on the line. The last turn based was Zero Company.

Turn based, visual novels or some light hack and slash games are my usual poison.

Chinese checkers

Judge Dredd: Helter Skelter (Wildlands boardgame reskin)

Like an ultimate crossover story from 2000AD. Stronts, Judges, and Slaine battling it out.

https://www.boardseyeview.net/post/judge-dredd-helter-skelter

Grognak and the Ruby Ruins, one of the Pip-Boy games you can collect in Fallout 4. Surprisingly well made and engaging.

Fallout and Fallout 2, natch

Yes.

Anything by Julian Gollop (all the way back to Chaos, Rebelstar, and up to Phoenix Point)

Fire Emblem

The ancient war games by CCS

Theatre Europe

The first Fallout games. Turn based isometric top down RPG.

They were awesome stories and I spent hours finding as much backstory as I could. By reading and searching every location.

Really loving Persona 5 Royal. Though I'm enjoying the life sim more than the action, I do still like turn based games, all the way back to FFVII on the PS1.

Star Wars knights of the old republic was the only game I enjoyed turn based combat. Generally I don’t like turn based combat. I prefer real time combat like command and conquer or supreme commander.

Disgaea, dood.

The Like a Dragon games from the Yakuza series are turn based. You can move around and interact with the environment and party members during character turns, so I feel a bit more involved than just issuing a command.

I didn't think I'd enjoy it after the more brawling style of gameplay in the other games, but it works well for the story, and they feel like their own thing rather than just another iteration of the same with a different MC.

I play JRPGs a lot, but the best one to do this right is Etrian Odyssey, mostly because you can make combat (inputting + animations) really fast, and make even normal enemies interesting challenges. People don't complain about having to wait for your foe in chess, and that's because it doesn't take you 5 seconds to move a pawn, and the foe is usually a fair challenge. (Arguably, video games can be even better at this than chess, because the AI doesn't need time to think. Instead of smarts, it usually has the stat advantage)

SMT(including Persona) generally does this fine, and Fire Emblem can either look decent with animations off, or speedy enough even with them (most of the time is spent thinking than waiting, either way - the goal). Those are my top 3 series.

On the opposite end, mainline Pokemon might be the worst turn-based combat I ever played, even if the mechanics are solid. I don't want to wait 3 seconds just for "crit + effectiveness + fainted" to display, even more so if most of trainers and random fights aren't challenging.

I'll throw in one with a real-time turn-based combat system: Megaman Battle Network The actual fight part is real time but you get to do the strategy part in turns

Seriously, nobody plays Dragonquest here? Not even 11?

Lately I have been really enjoying mewgenics. Very deep game

Birth of the Federation

(Most of my other ones have been said already)

I recently played Chained Echoes, and it was alright for being a fairly blatant Chrono Trigger/SNES era Final Fantasy ripoff. Decent combat, great sprite work, ridiculous story. JRPGs used to be my favorite genre, then they kinda went to shit IMO. They are making something of a comeback with people my age being nostalgic about the good ones making similarly good ones again.

Rarely. For some reason I had a ton of fun with Field Commander on PSP. For its time and console limitations, it was excellent.

Diplomacy is amazing, although I've only played it a few times and not at a high level.

FFX will always be my favorite, I still think it's the best story of the franchise. Other ones I like are Golden Sun, FFIV, Super Mario RPG, Crono Trigger was good too (just played that for the first time). Lufia I and II are worth mentioning while I never beat them start to finish I was often at a friends house who had them and watched a good deal of it. I'm gonna try to play those soon, I recall liking the story but I can't remember too much of it anymore.

All the time. Four-guys-in-a-line is one of my favorite genres. Final Fantasy 6 might be my favorite one.

More recently I quite liked Dungeon Antiqua 1 and 2, which are indie games. 1 is like "What if Final Fantasy 1 was slightly more like Wizardry (and also just one big dungeon)?" and 2 is like "What if Final Fantasy 3 was all dungeons?"

Wasteland 3 (I've only played that one)

Bag tag

So I've only seen a couple hours of gameplay (watching a friend stream it). But Jeanne d'Arc seems pretty interesting. More of a tactical turn-based RPG.

I do prefer it for games with stat-based combat. Pokémon, Advance Wars, Fire Emblem, Baldur's Gate 3, Pillars of Eternity, Into The Breach

I've been playing Disgaea which is really solid.

Golden Sun is my favorite turn-based system of all time. It gets really deep without being too complex to understand. You can get really creative, I always respecced Mia to be a DPS with volcano attacks instead of a water healer like she's supposed to be. And once you know what you're doing, you can change character class in the middle of battle.

The original Persona 3 combat system was also really good. If you played P3P or P3Re, it's not the same. P3 and P3FES are the only ones with the original "one more" system. They ruined it in 4, bloated it in 5, and bloated it beyond recognition in P5R.

NetHack

As far as a video game goes, I think that Persona 5 made it fun because it had enough of a progression and twist on the series’ standard mechanics.
