I never played one or two, so I can't compare. I di know a major reason I like f3 so much is because I am born and raised just outside of dc so I can relate to many places in thr game, especially the metro. And since Bethesda is also just outside of dc I love the small inside jokes they've placed in the game for us. That plus I have always wanted a morrowund/oblivion game set in the present/future with guns and technology. Also for any avid f3 fan, I HIGHLY, and can't emphasize that enough, recommend what I call "The Bible", aka the fallout 3 strategy guide. It is well worth the $20 price tag. Has everything you could ever have a question on.

hmmm i would say that 3 owns all, 1 and 2 were good as i was told, idk maybe i was mislead. but since i played 3, then i would hope 1&2 arent better but i look at it as if 3 was the one with the biggest upgrade :P

Ah yes forgot how fun Stealing Independence quest was.  I like talking to that robot with the frilly wig ha. 
 
Also I found that the speech challange was really easy when you know who to talk to.  You Got to Shoot Them in the Head quest I got 16 speech checks!  I had the 50 done before I had the lockpick, hacks, and even monster/people kills!  I found the hacking one is limited and got the trophy the same area I got it the first time... the vault with Falkes.
 
So I was playing on Normal and finished all the original main quest and main side quests, along with getting 14 bobbleheads, and the Anchorage dlc but I'm still only lv 28!  That's a lot of exp

What do you mean I don't have a life?
I'm a gamer, I have tons of lives.
