Both Gamespot and IGN have placed their reviews of the game. Gamespot giving it a fantastic 9.6 whilst IGN gave it an outstanding 9.9.

From Gamespot's 4 page review:

With its strong story, well-written dialogue, terrific voice cast, impressive graphics, great in-game sound, and extremely entertaining and varied gameplay, Grand Theft Auto: San Andreas is a stupendous thrill ride that shouldn't be missed.

From IGN's 6 page review:

that's why San Andreas is so awesome: it's a world that can offer different people different things. If a solid storyline and some incredibly tough missions are all that you're looking for, then you can have them. If you'd rather spend your time doing nothing but exploring the city and finding new ways to make money, destroy property, and dress like a pimp, then you can do that too. Live the life you want to live, do the things you want to do; it's entirely up to you. But however you choose to do it, do it now. Drop everything and do it right now. This is the best PlayStation 2 game ever made. Period.

IGN have also posted a guide for the game which IGN Insider's can read here
