Well its finally here, the game to end all games of its genre. If there are any other games like it.
GTA IV will blow you away, the first time you start playing it. You can tell straight away how much effort has been put into this game, everything down to the tiny scratches on your cars have been thought off. The realism is one of the best things about this game. Previous GTA's didnt have that much, you could crash into anything without many consequences.
Now however crashing too hard to the front will send you flying out the front window. Crashing the side of a wheel can cause it to buckle and stop the handling and speed, and if you get too fast you can burst the tire and set the rim on fire, or even kill the guy in the car in front. The cars are still the same old GTA, made up names which are nearly identical to real life cars (get the infernus then look at a pagani zonda!) but still if you have played GTA before you will love this. You still get the same sense of freedom, you can go anywhere you want.
The graphics in this game, are stunning. Compared to what we are used to with the PS2 and Xbox, you can tell Rockstar have taken full advantage of the next gen consoles power. You may still get tiny frame lag when large explosions happen, but that will happen regardless.
The story of GTA is typical of the series, you usually have killing missions, collecting missions etc. As you work your way to the top of the pile of crooks and gangs. There are also more imaginative missions, such as a bank heist, or hanging onto a speeding truck so you can hijack it.
Rockstar have followed suit of GTA SA and made the game work huge, but they havent restricted the realism to cars too, on the streets you see people sweeping, fixing engines, or getting stuff out the trunk of a car. Depending on what you drive, you can cross the 3 main islands in around 5 minutes. There are 3 main islands and 3 other smaller islands. You are a little restricted in the air however, there are around 3 helicopters but thats all i have found.
Around Liberty City there are loads of things you can do with your dates or friends (they have there own like, fondness levels, a bit like the sims) such as bowling, darts or drinking. There are also Burlesque strip shows and a comedy club with real life comedians, such as Ricky Gervais.
The game also lets you choose different things, whether you kill someone or dont is usually the choice, they affect the story by the cutscenes and the final mission, some people you save may come help you.
The cutscenes are another amazing feature, they are well acted and well animated. They make you laugh and they make you shocked. Especially with Niko Bellic the main character, who you will learn to love.

There are a few graphical glitches like all GTA games, you drive too fast and it still takes about half a second for things too appear, but it is usually the road and nothing serious like traffic or buildings.

Long review but meh its a great game! You should definately buy it.
