fallout 3 did have bugs. i've read of people who haven't been able to even play the game 6 months after release. i personally have had to abandon 2 games with ~75 hours of gameplay in them because of bugs. the first game was ~15 hours long and gfwl fucked something up. the second game was ~60 hours long and the 1.4 patch (which was supposed to do almost nothing) managed to change my stable, unmodded, working game into crash-to-desktop-within-2-minutes of entering the game world. saves wouldn't work, new games wouldn't work, nothing would last more than a couple of minutes. and since it was a steam purchase, i can't even go back to 1.3 and play my game unless i torrent it.
so to the dumbass who stated that it was a fact that the game was nearly flawless, you wanna tell me the story of the main quest? i'm still at the part where the guy in megaton wants you to go to the galaxy radio station.
