Subman don't waist your money on Fallout 3. Its only going to have graphics that is all. Everything else will suck big time.
Plus its a rippoff spoof of FO series.
The only canon is vaults, the suit and some other names. Everything else is re-invented according to Pete Hines.
Wait till some of the suckers buy it first and then see after a few weeks when you read about the good bad and the ugly.
You may regret spending the cash...
Anyhow its oblivion with guns.
