I don' t buy the " i don' t like PSP games because they' re no good for playing on the move" bullshit. GBA was essentially a SNES and the game' s were just portable versions of console games. It wasn' t until DS arrived that some people changed their minds and decided that what they wanted wasn' t to be able to play console-esque games anywhere, but instead games they could just play for 5 minutes at a time.
It' s called portable gaming for a reason. It' s like console gaming, but portable.
DS has a lot of games, but i prefer PSP' s lineup. There might be stuff on DS that can' t be done on another platform, different and unique experiences, ...but you can' t play Tekken on Metal Gear on DS, so DS loses.
In my opinion, the best games on PSP are:
Ratchet & Clank: Size Matters
Tekken: Dark Resurrection
Ace Combat X: Skies of Deception
Grand Theft Auto: Lberty City Stories
Grand Theft Auto: Vice City Stories
WipeOut Pure
Syphon Filter: Dark Mirror
BurnOut Legends
BurnOut Domination
Metal Gear Solid: Portable Ops
Daxter
LocoRoco
Killzone: Liberation

The Warriors
Every Extended Extra
Twisted Metal: Head On
Mega Man Maverick Hunter X
Virtua Tennis World Tour
Metal Gear Acid 2

...and im looking forwards to:

SOCOM: U.S. Navy SEALs Tactical Strike
Final Fantasy Tactics: The War of The Lions
Monster Hunter Freedom 2
WipEout Pulse
God of War: Chains of Olympus
