Hey guys, just got a PSP 3000 this weekend.I got the MGS Peace Walker entertainment pack(epic green psp).I also got a PSP starter kit and Killzone Liberation(which is HARD).What games do you guys suggest I get?Im planning on getting Resistance Retribution this wednesday and Portable ops sometime this month.What games are PSP's best exclusives?Doesnt matter what genre, I still want to know.

And any info or tips on PSP would be appreciated.

Cheers

Get MGS4... oh wait!

The best PSP games are JRPGs, lol.

Also Daxter and God of War: Chains of Olympus.

Here are some recommendations:

God of War Chains of Olympus and Ghost of Sparta

Kingdom Hearts Birth By Sleep

The 3rd Birthday

Resistance Retribution

SOCOM Fire team Bravo

Valkirya Chronicles II

Jailbreak it. And get Work Time Fun.

I heard somewhere about a Halo game on PSP. It's not official, but I think some guy in his basement used the Combat Evolved engine to make some sort of Halo game playable on hacked PSPs.

EDIT: Nevermind, it was done as a standalone Quake 2 mod built for PSP.
