This one is easy for me owning so many PSP games.
Folklore (PS3) - One of the very few games to make good use of Sixaxis, great design, and cool comic style cutscenes.
Crush (PSP) - Very unique puzzle game, "crushing" between 2D and 3D to solve puzzles
Disgaea: Afternoon of Darkness (PSP) - Whole series in general is underrated, but this game was my favourite
Metal Gear Acid 2 (PSP) - Underrated series in my opinion, very different for a metal gear game, but an awesome card collecting, turn based game.
Jeanne D'Arc (PSP) - Great SRPG, up there with FF Tactics and Disgaea, bit simpler but cool story and design
Wipeout Pulse (PSP) - Wipeout Pure did good but this absolutely bombed, unfair for such a fun racer
Dungeon Siege: Throne of Agony (PSP) - Surprisingly deep hack and slasher, still a good buy today
