If so, what do you think so far? I've got about 30 packages, only 3 missions done, I went for the packages first, even though the rewards aren't as useful as in GTA3, its just easier finding them without people shooting at me.
I think people might be a bit disappointed if they were expecting a revolutionary new game. This is actually just more of the same. More of an expansion pack feel than a truly new game. I still love it though!
