Do you base "awesome graphics" on just the visual fidelity of a game? What about the amazing architecture? What about the sheer vast amount of objects moving around on the screen? Have you taken the time, in this game, to stop and just look around and see what's really going on around you? All the cars moving about--some even hit each other--or people walking around and on their way to an appointment or coffee or food, doing their own things. What about the environmental weathering (have you seen a heavy rain pour yet or how about the fog rolling in? It looks like nothing else I've seen in a game).
Nothing, here is cookie cutter. Every single corner and alleyway has been uniquely designed and there is probably still over 80% of the game that you still needs to see (a guess of course).
In past GTA games, walking through any door (when outside) would mean you were going to see a loading screen. Resturants, Bars, Gyms, and everything else was not immediately accessible. Now, walking through a door and immediately have access to these things still trips me out. The first time I did this (I was cloth shopping

) it litterally made me stop and think about what had just happened--and then I killed everyone in the store because I was so excited.
Anyone who's played any of the previous games knows that GTA has never ever been about the graphics--it's always been kind of understood that that aspect of the game just wasnt going to blow you away, so this is a huge improvement!
This is not Gears of War where you're running down brick/rock/steal hallways--this is an open world with a really impressive draw distance with hundreds, maybe thousands of things going on at once. I personally think the game looks stunning. There's more to a great, visually impressive presentation than the resolution of a brick pattern on the side of a building. Take some time to stop and look around you.
