Depends what sort of games you like/looking for.
Pokemon games are always nice RPGs.
Sonic Rush games are nice if you're a fan of the old 2d sonic games.
For an FPS, Metroid Prime Hunters was pretty good, not amazing but still good.
Randomness, gotta go for Wario Ware series.
As for an open-ended game, Animal Crossing is a nice start. Gets boring after a while though. (Took 8 months for me to get bored xD)
Oh and something for PC that I'm sure you'll like the look of.https://www.youtube.com/watch?v=QJSjZwVvZYQ
