The three-city map of San Andreas (~36 km²) is far larger than Liberty City Stories (~8 km²). The PSP cannot stream the world fast enough from UMD.

There is no standalone Grand Theft Auto: San Andreas (original 2004 PS2 title) released for the PlayStation Portable. Instead, the PSP received Grand Theft Auto: Liberty City Stories (2005) and Grand Theft Auto: Vice City Stories (2006), both built on a modified San Andreas engine.
