Of late, I've been thinking of buying a PSP. Not for it's flashiness, or ability to play movies or any of that, it's just some of the games look fantastic. Games I'm interested in buying are...

Metal Gear Solid: Portable Ops (main selling point for me)
GTA Vice City/Liberty City Stories
Killzone: Liberation
Gun:Showdown

So if there are any PSP owners out there, could you please give me your opinions, and tell me any other useful info I should know.

Cheers. Ash.
