Which game should I get?

I just got $5 off coupon from PSP underground. I want to know which game to buy I want a good game that doesn't have a short story and is really fun. I work two nights till the morning so i need something to keep me up. This are some games I'm looking at Lumines II, Need for speed Carbon, GOF Chains of olympus, rainbow six las vegas 2, NBA street showtime, and some soccer game. I really want to know if ya played any of this games and see what ya think about it. If ya have some other games ya played that you think is good let me know.
