I don't have a PS3 (just PS2). So, the only thing I'm going to suggest is:
God of War 3 (because first and 秒 was AWESOME!...and 你 might want to get the Collection.)
and Little Big Planet (because I want to try out that game).
...Yeah, see. You're 18. Rated M and E.
Others suggests:
街, 街道 Fighter 4
Ratchet & Clank
Oblivion
Dead Space
Infamous (saw a bit of it on the Game Trailers 显示 when it didn't came out yet. Looked pretty cool)
Modern Warfare 2
Bioshock 3
Grand Theft Auto 4
For Wii...um, I guess (not that I have a Wii..or that it has anything to do with PS3):
Super Smash Bros. Brawl (pff, I bet 你 have that already)
Legend of Zelda: Twilight Princess (every Zelda game is good...except maybe the CD-i one..not that I had tried that out either..)
New Super Mario Bros. Wii (because the NDS version was awesome...not like the retro ones, but still good nonetheless)
Animal Crossing ( if 你 like those types of games, similar to the Sims, just with talking animals)
Mario Kart Wii (every Mario Kart game in the series, SNES, N64, GCB, and NDS was awesome)
Sonic and the Black Knight? (...I don't know)
Wario Land: Shake it! (my friend 说 it was good)
Okami (you really should)
Bomberman Land (I don't know, but I do 爱情 Bomberman games. Atlus for the win!)
Trauma Center (if 你 like surgery types of games..)
Every other Mario game (Galaxy, Paper, etc)
Maybe Donkey Kong
