Introduction

Actually there are 3 version of San Andreas:

1st - PlayStation 2: Original release of the game
2nd - PC/XBox: Port of the PS2 version that improves graphics, but looses some features from PS2
3rd - mobile port: Modified version based on PC port and released on iOS, Android, XBox 360 and Windows Store. Like the PC port, this port improves some textures fro PC version, but most of the stuff has worse quality.

Here I´m going to explain how to get the bes from every version of this game.
