just got my copy of this a couple days ago, and so far i have to say it's good to be back in the Fallout universe.

i've only played about 7 or 8 hours but i feel its already an improvement on Fallout 3.

playing on hardcoe mode isnt so bad.

overall im enjoying the game and think i'll put at least 150 hours into it, maybe more

ull put more because u have to chose a faction at the end, so unlike fo3 where there was 2 endings before broken steel broke it, u have multiple different endings between 4 factions all of which were done very well....well legion seems shafted on content but still good though.

do u save before you make the choice who to support, then go back to that save to choose another?? rinse and repeat??

Doesn't work that way. You don't choose who to support at the very end, you kind of do that all throughout the game. Your actions can and will affect each factions' opinion about you, and it's very possible to permanently stain your reputation with someone and hence make allying with them impossible. You can try to play things neutrally as well, but if you don't pick who your friends and enemies are, they'll eventually decide for you.

oh ok, so multiple playthroughs it is then
