- Battle for Wesnoth is one of my favorite turn-based strategy games.
- Dungeon Crawl Stone Soup makes a whole day disappear when I play it.
- Tales of Maj’Eyal is another, slightly more graphically rich roguelike. I haven’t played it too much, but it seems like there’s quite a lot of content to it.
- The Ur-Quan Masters… I don’t even know how to categorize it. It’s tough as nails, but the art style is rich, and the worldbuilding draws you in.
Any others I would have mentioned are already in other comments.
I love seeing Godot games do well.
