I’ll recommend in a different direction. Abomi Nation on Steam is basically like if Pokemon were built around Nuzlockes challenges. Often goes on sale for only a few bucks. It doesn’t have any real Pokemon, but I really like the designs.

If you’re looking for other games to play, check out RetroAchievements. They have all kinds of events and stuff to reduce the “decision paralysis” that can come from having access to way too many games.
