I always thought it would be cool for a Mafia-esque type Grand Theft Auto. But that is just my opinion, but I'm currently not anticipating for a GTA5, I'm still waiting to get GTA4, Lol.
I do like San Andreas, but I think I liked GTA3 better, mainly for the fact that it's the first GTA I've played.
Anyway:
I want blood-spilling action, a great story, more guns, more muscle cars, and a nice cup of hot coffee, that would sum up a great game. >
