Video Games Anything Currently good on PSP

[far2000]

h GUYS, I had a psp when it just came out, and i must say was disapointed with games out during that time, so i send it of 2 my sister, but i feel i need a small handheld game , especially during work and once again thinking of goin 4 the psp, is there any games out there that are mind blowing and can be played all the time..

a few that im thinking about are: 1.killzone,2. Call of duty 3. Ace combat

any1 played these? anything similar?

thanks
