A great part of the PC version of Grand Theft Auto: San Andreas is the possiblity to modify it: Rockstar claims to have left important game data files unlocked and in text files as opposed to hard-coding them in the game. Although Rockstar lists "player modifications support" as a feature, it's safe to assume that Rockstar will not be providing any game editors with the game, and we can expect to be able to import additional player skins, probably in the form of clothes. Player models are at the moment split into around 10 different pieces, with two of each for different fitness levels. As such, player skins as seen in GTA Vice City are unlikely, unless we are provided with a custom slot with a single static mesh skin. Bear in mind that this is simply speculation at this point, as nothing solid has been confirmed yet.

It was decided that the PC version of San Andreas will not have an inbuilt 2-player mode as "the dual keyboard and mouse set up proved too unwieldy for players and didn't work with the PC version of San Andreas' greatly improved free camera mechanics. Rockstar North decided to focus on maximizing the single player experience."
