Mine was:
Prince of Persia Revelations
What's yours?
japanese ridge racer. i got mines via import with my psp because it was released a year earlier in japan and was still cheaper then when it was finally released here (psp and the game was cheaper than just the psp here). yeah i had to put up with the foreign language but wth - its a racing game, text don't matter.
POP Revelations i think, same as you
Or possibly Untold Legends: BOTB
And, unlike most people, i liekd both
FIFA World Cup Germany 2006 (won it with my PSP) :D
Wipeout Pure also.. bought @ same time as first psp... second was GTA LCS for downgrading
Legend of Heroes 2: pro. of the moonlight witch. (it's an rpg)
