Feels kind of like Fallout and Borderlands banged, and had an illegitimate kid named Rage.
Where the game is really lacking is the substance. The missions are very short, very simple, and really are not that involved. I won't complain about the story itself, as I think the whole purpose was for the main character to wake up one day, and just live. Just work to repopulate life on earth. Basically though, you drive for 2 or 3 minutes across a wasteland that really does not have anything in between the few places designated as quest zones, so there really is no chance to get out and explore anything. You will run across enemies in the same places every time. It never changes. Once you finish your drive, you leave the buggy, go into the quest zone, and 5 minutes later, your done and on your way back to the buggy, for a 2 to 3 minute drive back from whence you came. Its really annoying, and really quite boring. The gun play is very run of the mill. I am just under 10 hours, and I still have not crafted any ammunition. I have crafted a few bots and whatnot, but they really are not all that exciting. The game feels kind of like Fallout and Borderlands banged one another, and had an illegitimate kid named Rage. Albeit a slow, uncomprehending child, named Rage.
The Racing mechanics absolutely suck. Its not that the vehicles control poorly...though they don't control great...its that the racing component could have been made to be a much more complete experience. Instead it feels like simplistic, time wasting filler. Most of the races you do are 3 laps, and then you are done. Three short laps, with races generally lasting no more then 3 minutes or so. It is a huge disappointment. Suffice it to say, I really hate the Racing in this game, and I have seen and heard many other people complain about it for the same reason. They are right.
All in all, I am really disappointed with this game. I was really expecting id Software to come out with something insane, given that they are responsible for such incredible shooters as Doom, Quake, and Wolfenstein (though the last few wolfensteins have not been that good either...).
While its definitely worth checking out if you like shooters, is it worth 60 bucks? Absolutely not. Is it worth 30? Definitely. If you like shooters, I encourage you to check out Killzone 2 or 3 if you haven't already. They play much more soundly, and are generally a lot more intense and fun then Rage. Its ultimately a very shallow experience. It looks pretty, thats about it.
