First off, this has nothing to do with this section. In this section you are supposed to discuss Grand Theft Auto San Andreas, not the newer ones. Yet, as I am not moderator; I will answer that question.
Let's begin with the fact that GTA-5 hasn't been released yet. Only a single trailer was posted, and there's nothing about game plays. No one played the new Grand Theft Auto in this community, so no one can answer this question. GTA-4 on the other hand (in my opinion), isn't that good, as a fact I can say that's it is much worse than GTA SA. The story-line is quite interesting, yet the rest of the gameplay really sucks.
