Great game, but be warned:
I had major problems with the PS3 version and I took it back and got the 360 version and still had problems.
Some people never experienced a hick-up (my brother), and some people had their consoles burn to the ground. And between those two extremes is the buggiest game I have ever played in my life.
I am not sure what the Fallout3 forums look like now but when I was on them there were literally tens of thousands of outraged gamers who were severely pissed off at how bugged out the game is, 360 and PS3.
Of course all of our honest hard working critics at various sites overlooked these glaring flaws with the game and instead decided to blow smoke up Bethesda's ass.
Still, it is a very good game and yes you should give it a go. Just cross your fingers.
Fuck... I'm dead!
