>>41020065Pokemon Gaia is a GBA ROMhack and unironically the best Pokemon game ever released in my opinion. Has a lot of QoL features like reusable TMs and physical/special split, mons from future gens including fairy typing, a huge amount of new assets including a completely original region and story, and overall is just an incredible fanwork.
Clover is also great too if you don't mind some old memes and weird difficulty spikes.
