As a long-time fan of the classic Fallout games, my first impression of Bethesda's baby was: what butt-vomit did I just pay for? It felt clunky, buggy and way too similar to a game that starts with 'O' and ends in "fuckyourself." Yet soon after I stopped sleeping regularly. And I stopped caring about whether it was or was not truly Fallout.
Yes, this is Oblivion done right. With guns. Less fat, tastes great. If you enjoyed TES4 for what it was, then you will enjoy this game at least twice as much because it has exploding baby carriages and 4000% more needless decapitation™. VATS is truly awesome--take the work out of Max Payne's bullet time, add some (mostly) well-done random camera work and turn up the number of bloody jawbones flying around.
Bethesda has wrung every last drop of beautiful out of my computer, even shaking off the gross little hairs underneath.
