I finally got GTA San Andreas for PC yesterday and I was impressed. If you are expecting Half Life 2 or Doom 3 graphics, look elsewhere. These are GTA graphics, but more refined and higher quality textures than on the PS2. I pumped up the resolution to 1280x1024 (my lcd's native resolution) and it looked pretty nice. What I liked best was the fact that you can actually see items in the distance without jaggies and blurry textures. I only bumped the Anti Aliasing up to 1 sample because my hardware is a little dated. I set the graphics to very high and my computer has no problems running the game.
The game came on DVD in a nice hard bound booklet. The booklet is a City Guide for the three cities of San Andreas. It gives details and info on some of the places that CJ will encounter in his journey.
I had this on PS2 when it first came out, but I soon lost intrest in the PS2 graphics and I sold it on ebay. I only made it about 20 percent through the game so there is a LOT of gameplay left. I don't mind.
