Treasure behind waterfall

If it's the early 2000s driving elements.

Lockpicking and pickpocketing.

Double jump.

Barrels!

Useless loading screen tips

Character customization including eyecolor and jaw shape.

You already included card battling, covered there...

The word "roguelike" in the description (actual roguelike mechanics should not be included if you do this) (alternately, "souls-like").

Some time of variant movement speed. Analog movement, Walk/run toggle, some type of dash/roll/slide etc. There needs to be something or I am slightly angry the whole time.

Not being able to kill children (while being able to kill virtually anyone else at any time) has been a Bethesda thing that's made its way into other games either as a real mechanic or as a bit of a joke.

First aid kit.

A platform section for no reason whatsoever even though your game engine is not designed for it and it sucks all the fun out of the game for about 5 minutes of dying to get past 15 seconds of actual game.

"Quirky" loading info. Initializing graphics. Booting level. Rendering shaders. Kicking the dog up the arse.

Pause menus and any game menus shouldn’t be closed by Any loading or screen transitions. Like how destiny lets you be in your inventory or map/other menus while you load into matches in the background

• Painted ledges for climbing
• Compass in open world games
• Crafting
• punching trees/gathering twigs to creste basic tools. (Seriously, so many survival games start like this)
• random stealth section for no reason, and it you get caught it's game over.
• Title that the first 2 words start with A and C.
• Title that usually has some variant of "Remaster", "GOTY", or "Next-Gen"
• For card games, mana system because so many card games have this for some reason.
• party members who usually use inefficient moves against an enemy.
• hunger system where you need to eat 3 whole turkeys to get your hunger back up to 100% after losing 75% from sleeping 5 hours.
• Day/night cycle with sleep that just drains your hunger/thirst stat, but raises your HP to max.

I could go on, but this list is long enough. Ironically, only 1 thing on this list relates to card games.
