I got Fallout 3 as one of the presents from my sister. I just started playing last night and so far I like it. It is very different from any game I've played before. I have a feeling that this could take some serious time to play.
You have NO idea.... I'm 70 hours in, but I'm a completeist and trying to get as many achievements as I can. I'll have to play it through at least two more times to unlock all of them (You have to be a goody goody, a neutral, and a baddie to get them all)... Plus the 20 bobbleheads achievement and the kill all the supermutants will be near impossible to pull off....
As for other games, these hit our household in 4Q2008 (to either me, my daughter, or my son)...
All 360 games (no wii games asked for strangely by either of them)
GTA IV (I know, somehow missed it earlier this year)
Call of Duty: World at War
Gears of War 2
Fallout 3
Star Wars: The Force Unleashed
Scene It! Box Office Smash
Sing It
Dance Dance Revolution 3
Turok
The Orange Box
World Series of Poker 2008
Yeah, I'm gonna be busy for a while.... ESPECIALLY since I've sunk so much time into Fallout 3 already.
