First, Kentarou, I have to say:

My PS3 makes me so happy! Congratulations on getting one!

I only have one game for my PS3, MotorStorm (it was the 80GB bundle). I really only use my PS3 for music, internet, movies, and my old PS1 and PS2 games. I myself am wondering which games to get

So far I want:

FFXIII and Versus XIII (duh)
Little Big Planet
Heavenly Sword
Soul Calibur IV
Tekken 6
DMC 4
Sonic Unleashed
Gran Turismo 5

Oh, and get a DualShock 3 Controller

Again,
