The PSP games you have to own

Pilot Academy
ByRising Stars| Out TBA

This huge flight sim covers everything from military fighters to heavily-laden jumbos, setting them free in three 64km square worlds at up to 30,000 feet. Fighters range from WWI to modern day, while civilian machines include crop dusters and stunt planes. Single-player will challenge with emergency landings and harsh weather, while up to eight can dogfight via WiFi – even if they don't have the game. And until we get a firm US release date, we have to suspect that quite a few folks over here won't have it.

Even if there were 100 flight sims on PSP, this would still be massively promising.
