All i've seen is videos on YouToob, and frankly, it looked like GTA SA, which looked like GTA VC but a bit prettier which looked the same as GTA 3 but a little better.
Got a screenshot at "full size" that does it justice?
NO NO NO NO NO! GTA SA is terrible compared to this. The graphics are way better for a start. Sure, back in it's day, SA had unreal graphics, but now it's just terrible in comparison. It's nearly worth getting IV for graphics alone...
Then there's the physics, which are infinitely better than SA. Cars handle realistically (or at least, more realistic than SA), and there's rag-doll physics...which are just :jawdrop: lol
I imagine between the time you first posted asking for a screenshot, and now (several hours) you could have gone onto one of the hundreds of game news sites and seen as many screenshots as you wanted.
Regardless, you really don't get a sense of the atmosphere the game creates without playing it.
Having owned the past 3 GTA titles on both PC and Xbox each, I'd say it plays much better as a console game, this installment I feel will be no different. You're going to need a pretty wacky key layout to perform some of the commands.
Here's some ingame pictures for ya Jakg, they're bad quality, but their enough so you can see the atmosphere, as people said, you have to see it in motion in order to apreciate the great graphics, physics and atmosphere...
