Digimon is a better franchise in world building, characters and anime, but Pokémon takes the cake in gaming. Digimon games are okay, but not awesome.
Yeah, the Digimon games can be pretty hit or miss. Even if the main games are somewhat formulaic, there's a reason the Pokemon franchise has lasted as long as it has, and with as minimal changes to the basic formula that it has.
Some of the spinoff games are pretty fun too, like Pokemon Conquest for instance. Digimon has a special place in my heart too though, even if for the first 4 seasons of the anime (I think 3 is the best though
As for me, I mostly play RPGs of some type, though I'm especially fond of Tactical RPGs, though I have absolutely no problems with turn based or action RPGs.
I like stuff like Harvest Moon as well, or fun platformers or fighting games as well.
I'm into all sorts of things.
...We should probably set up some sort of casual Melty Blood Tourney at some point, that might be pretty fun.
