Highly addictive game, long story that's emotional (sorta) and has meaning.
Niko is a lot of fun to be, the weapons are cool, and city is huge and fun to play in. Also, it's funny when being Niko and he says things while killing people like "Why wont you stay down?" and "DIE!" Niko also just is fun to be, its funny when he's drunk and falls. Also, if you drink then drive, its hard to drive and the screen messes you up on purpose because your drunk and driving.
The story is also very fun, and very long. There are 93 missions, some hard, some easy, some a good length, all fun.
The gameplay is highly addictive. I love the free roam in this game. Also, the cars and helicopters (annihilator (spelt wrong)) are really fun.
The DLC kept me coming back, I'm getting Episodes of Liberty City.
Final, buy this game, don't rent, just buy.
