Bring your radiation-suit, because once you enter The Capital Wasteland you're not leaving for a long-long time.
You start this game as a character that doesn't even have a name, you're even playing through your own birth! You do also get to customize your character then, Oblivion-style. Then you follow your characters progression, with everything from dealing with bullies to shooting radroaches, which is just a overgrown roach. After some time, your dad gets into some trouble with the leader of the vault that you live in, and it's not until now that you actually think about where you've been. You've been raised in the vault to think that the outside world is a bad place to be, and that you'll be dead by dawn, more or less. But you need to get out now, because the leader of the vault can't find your dad, he's now after you, so you escape, after a painful(or not, karma!) goodbye with your best friend. You escape the vault, and when you see the capital wasteland for the first time, it's filled with a lot of mixed feelings. It's a very beautiful sight, but also horrible, Bethesda seems to be able to make most things beautiful. After this you need to find your dad, and you'll go on an adventure over the Capital Wasteland, that you wont forget anytime soon.
The graphics of this game is good, it's not the best of it's time. When you blow up a mini-nuke or a nuclear-powered car, the blast is amazing, and the whole screen shakes up, it seems very real. The sound too, is REALLY good, the sound effects are great, but the soundtrack doesn't work as well for me, to me it seems too much like a recycle of Oblivions soundtrack. And, when you're not to busy being in the Capital Wasteland, you'll feel Oblivion too much, and when I got Fallout 3 for the first time I had been playing Oblivion a lot, and I just couldn't bare to play Fallout 3 for a while, because they have too much of the same feel. Other than that, this game is great, and if you don't already have it, you really need to get it!
