Preferably one that's not a rom hack, though I dig those too. I'm looking for something a bit harder than the originals and maybe a bit more mature, but still fair and whimsical. I'd like a game with pokemon from as many gens as possible, and fakemons are fine too.
#1 Pokemon Vanguard is probably the one I'll play if I ever want to play a fangame again

Fix for any lag from the developer: "The engine the game is built with has a memory leak issue I'm not currently able to fix, if the game starts to lag, save and hit f12 to soft reset and you'll be good for a bit."

#2 Pokemon Eon Guardians is good except it has issues with lag https://reliccastle.com/threads/5445/ This is supposedly the fix for the lag
#3 Another that I know of is Floral Tempus https://www.rebornevo.com/forums/topic/38862-pok%C3%A9mon-floral-tempus-ex-v194-released-12-gyms-elite-4champion/
