I can think of a handful of games that, despite being games that I’ve enjoyed, never really became part of a “genre”. Do you have any like this, and if so, which?
Are they games that you’d like to see another entrant to the genre to? Would you recommend the original game as one to keep playing?
Diary of a Spaceport Janitor is a slice of life/poverty simulator in which you scrape by earning pennies, dreaming of escape and adventure. Full of charm!
Miasmata is a horror/cartography game where you have to triangulate PoIs in order to fill out your map as you search for a cure to your disease on an uninhibited tropical island.
Yoku’s Island Express is a metroidvania/pinball game in which you traverse the world vis flippers, chutes, and as a bug rolling a ball.
