Can someone explain about gta4 VS gta4 liberty city stories, china town (not sure if its china town), and etc?

GTA IV and GTA: Liberty City Stories are two different games (as is GTA: Vice City Stories and GTA: Chinatown Wars). Those are four different games. GTA IV is an original PS3 game, GTA: Chinatown Wars is a port of the Nintendo game. GTA: Liberty City Stories is a PSP game based on the city of the PS2 version of GTA III, and GTA: Vice City Stories is a PSP game based on the city of the PS2 game GTA: Vice City. This means they use the same city, but have different tasks. After the PSP versions of GTA: Liberty City Stories and GTA: Vice City Stories came out, they ported the games into PS2 games, which means it is the exact same game on PSP and PS2, the only difference is the controls because the PS2 has two more shoulder buttons. So to clear it up, all four GTA games are different games. GTA IV - PS3 disc based game GTA: Liberty City Stories - PSP and PS2 game - same city as GTA III (can be downloaded from PSN Store as PSP game only) GTA: Vice City Stories - PSP and PS2 game - same city as GTA: Vice City (can be downloaded from PSN Store as PSP game only) GTA: Chinatown wars - game ported over from Nintendo (can be downloaded from PSN Store as PSP game only)
