The Gameplay will definitely be better I think, they're really even making the interactions with your followers better too, having real conversations with them and even helping them with some of their problems, they're making it more of a roleplaying game than Fallout 3 was while keeping all of the great stuff that made FO3 good. I heard there might even be some perks to not using the VATS, like some weapons might work better out of it or something.
No you cant add your saves from FO3. Sorry.
If ya read its already been stated its not an add on :P 7 days to go now
