recommend some action/adventure psp games NOT RPG\'S

i've played not many but i've updated my system so i can't download .
i've got so far:

rainbow six vegas. good game, very good online
splinter cell essentials. best game played, but i'm stuck at a mission.
ghost recon 2: bad game
brothers in arms d-day: hate it i can't even point up XD
locoroco: love it, it isn't action/adventure but i just love it.

I want to buy assassins creed bloodlines and maybe more. could you recommend me some others, please?

i don't want to play:

god of war and metal gear solid.

 

Socom 3
Resistance Retribution
Kingdom Hearts Birth By Sleep
Final Fantasy Dissidia
Grand Theft Auto Vice City Stories
Dantes Inferno

 

ty i might give a try at GTA.

 

Ys Seven
Ys: The Ark of Napishtim
Ys: The Oath in Felghana
Kingdom Hearts Birth By Sleep
Final Fantasy Dissidia

 

I second Resistance, in fact, it's better than the PS3 versions imo.

Also Killzone Liberation is a good one. Medal Of Honor is another one.

 

LittleBigPlanet
Patapon
Shadow of Destiny
Cave Story (Homebrew)
Tales of the World: Radiant Mythology

 

Valkyria Chronicles.
