Fallout 3 looks like one of the best games I could ever play. Environment is absolutely enthralling, the creatures are fantastic and horrific, and the amount of detail put into the weapons as well as the majesty of the broken world you have to play in are amazing.
Too bad the game freaks me out too much to play it for any extended period of time.
My usual method of playing Fallout 3: "Huh, there's a cool looking creepy building over there, shrouded in shadows. I bet it would be cool to explore it...or I could make a wide circle around it."
