PokéRogue
pokerogue.net
A Pokémon fangame heavily inspired by the roguelite genre. Battle endlessly while gathering stacking items, exploring many different biomes, and reaching Pokémon stats you never thought possible.

There is a Pokemon fan Project that let you fight with a Pokemon team in a rogue lite format, so it get harder and harder and you need to find a team that keep up with the level and manage you money/ressouces as long as possible. I think it makes a lot of fun and maybe survive since it’s a non profit project. Try it out if you want.
