I collected some resources that can help in this post, like the aforementioned lemmyverse.net. Another useful trick I’ve found is going to instances dedicated to specific interests (like programming.dev) and browsing their communities list.
The first couple links in my post are kbin specific but the rest should be useful to everybody!
Oh another one I remembered: Magical Diary Horse Hall (and the sequel Wolf Hall) - absolutely loved the first but never got around to playing Wolf Hall
Funny, I was just thinking about this today as I was going through my Steam wishlist. I don’t even know what to call the genre but I want more of it. Haven’t heard of exocolonist before, so I’ll check that out. The only other one I can think of right now is Growing Up (Steam link), but that one is kind of shallow and not great for replayability.
Good thing I didn’t get Outer Worlds or Merchant of the Skies in the sale!
