Fun..but not perfect.
There are times in the game when i see a character on the street doing something so realistic that i become shocked. There are times when I just stare at the scenes and the tall buildings and become amazed.
There are also times when i feel tired of receiving so many phone calls from characters in the game telling me to take them out for some dinner or a night at the strip club. You have to keep so many characters liking you and at the same time work on some missions...it can get a little overwhelming sometimes. Of course, you don't HAVE to take your girlfriend out on a date if you don't want to...but hey if you paid 60 bucks for the game you might as well see everything the game has to offer.
If you buy this game, you may find yourself playing nonstop for a couple of days...but it you'll get over it very very soon.
