Scurge:Hive, Neves, Etrian Odyssey, Digimon World, Touch Detective, Jump! Ultimate Stars, CrossworDS, New York Times Crosswords, Picross, Zoo Keeper, Polarium, Sonic Rush, and SNES games, Klonoa 1, Kirby (All of 'em besides Squeak Squad), and a few other GBA games.
I'm also attempting to make my way through the essential games, as well as lesser-known-but-great games.
I'm entirely hooked on Scurge:Hive ATM, but I've been making my way on to Digimon World, Touch Detective, and Zoo Keeper a bit as well.
