I have no idea what people are getting stroppy about with this game... it is flinking awesome !!!
People are comparing it to the likes of Borderlands, but to be honest apart from being set in a post apocalyptic world, inhabited by psychopaths, general nasty people and the obligatory "wild west" theme... thats it. Borderlands, to be honest doesn't even come close to the quality of this fine game.
The graphics are amazing. Look totally authentic. Game play is spot on... it is a true homage to Doom; a game I'm sure the vast majority of the complaining gamers weren't even around when originally released !
The longevity of the game seems fine. I have only played 3 hours of the game so far, but it feels like I have barely even scratched the surface. Plus, when completed there is an extremely challenging multiplayer option that can be played single player too. As well as some vehicle racing (albeit a bit second rate).
In fact, the only gripe I have with the game is sometimes when turning around, the textures take a moment or so to update causing the landscape, walls, etc to appear flat and texture-less... Although it occurs few and far between, and is only for a second or so.
The game is that good, I'd give it six stars....
