I enjoy Dungeon Crawl Stone Soup played in the terminal with ASCII graphics. I wonder whether there are other hidden gems out there which don't get attention because they are "ugly"?
West of Loathing and its sequel Shadows of Loathing have a bland grayscale artstyle on the outside but they're absolutely hilarious RPGs that have a lot of heart to them.
Man I played their browser game way back when, the humor was pretty funny, but I haven't been able to make time to consider trying their console games.
