I don’t play this often enough lately but Jigsaw Puzzle Dreams is a super simple & cosy game. It’s jigsaw puzzles, yes, but you also get to decorate the apartment where you’re doing the puzzles. It is just a very chill, no-pressure time and often I will just mess around doing the decor side of it so I have a few different apartment vibes to choose from for when I finally decide to do a puzzle. When I get super sad & unmotivated I will do a really small easy puzzle on the bedroom desk and it helps me to get the feeling that I have completed a thing, which is sometimes enough to help get me moving on non-game things.
For mine there was very little for me to tinker with, it was a single player Azerothcore repack ready to go, which is good because I am not very technologically skilled! There have been a couple bugs, like a couple of quests are kinda janked, but I can just go into the database and mark them off as done for my character when that happens cos I don’t know how to properly fix them. Most of the tinkering was things like, do I want to adjust reputation/skill gains, how much stuff do I want the auctionhouse bot to list, how many profs do I want to allow per character, things like that. But that was all very easy to do thanks to the way the repack was done, and isn’t actually necessary because you can just stick with the default settings. The only thing I can’t do is PvP because I don’t have playerbots, but I never did PvP on WoW anyway so it doesn’t affect me much. I prefer it a lot to most of the multiplayer pservers I have tried, but I did tend to play WoW as a single player game mostly anyway! :D
