Every so often i'll ook for games that have wifi, but just looking at lists of games with wifi gets me no where since msot of them are stupid wifi things like a score board, sending mail to others with the same game, etc.
I like games like Castlevania (have them all on the DS) Kingdomhearts (have the ds, no wifi though Dx), Pokemon (have platinum, does heartgold and the other have any extra wifi features?), MP hunters (prime series was so destroying metroid, glad it's over).
Looking for co-op games and ones where you can battle other players.
Generic rpg's doesnt do anything for me these days. Golden sun was good for its time, but the actually battle system was too generic as a rpg, spam strongest attack, heal, winrar. Pokemons battle system is a twist which makes me like it, so anything that makes a twist is golden.
