The best GTA game in my opinion is still San Andreas, no doubt about it. Although CJ was not the best character from the series (second behind Trevor), I enjoyed the dynamics involved in being able to mold CJ to be fat, skinny, or muscular and have three (four if you count the default) different types of fighting styles - all of this is lacking in other GTA games. More over, San Andreas introduced car modifications, jet-pack, gambling, truck-rigging, monster truck, animals, bicycles, turf wars, foods and drinks, and innovation. I still play the game from time to time.
