It's been a long time since I played a soulslike and finally booted up Lies of P this week. Pretty cool, specially with mods since it hasn't been performing too well on my Linux rig, but I'm more grateful about it's accessibility features than anything else. Can't praise it for it's level design with it's linearity and so many assets placed without measure, logic or purpose, even if the overall victorian/belle epoque vibe is appealing. On a positive note it's clever audiovisual cues during combat reminded me of a past discussion of yours.
As for locations, this is something I'll probably want to edit later as more come to mind. Majula is what it is. Love at first sight. Also the Duke's Archive combined with the crystal cave below was pretty neat, but it's not the only descent into the abyss I've enjoyed in Dark Souls. I spent some time months ago setting up a Runecairn campaign, which is basically a norse soulslike TTRPG. I sadly discarded that and started testing Mausritter, but I was a bit hyped about some things I had come up with for Runecairn. Shame.
