Had a chance to try this out on PC.
The story and setting are very similar to fallout 3, it's a generational leap in terms of visuals though. Strip all the rpg elements and VATS from fallout 3 and replace them with the ability to drive vehicls and extremely satisfying gunplay and you'll have a very good idea of what to expect.
You can combine the loot you collect to create items like in fallout 3. The NPCS are very well designed, all of them are unique and the female characters are hot as hell lol, don't expect to run across the same character model with slightly different colors every few minutes.
Technically the game needed more polish, let's see what updates they release in the future, the underlying tech has potential though, I don't know how mod friendly the engine is but I'm expecting to see some great stuff in the near future.
I played it a bit more and the amount of low res textures is really disappointing, the game can look very good and then look like shit in a matter of seconds. There's no excuse for this on the PC version, what the hell ID?
