i constantly replay both fallout 3 and 2
currently, im re-doing fo3 at a higher difficulty, and the ghoul reavers are KILLING me
and
i have
NEVER
blown up megaton.
pff, i use the console, and get myself the tenpenny suite key anyway. big whopp
cant customize the apartment tho, but who cares.
and as for character types, in oblivion, yes they differ, check the various stats.
orc is typical warrior player, blunt weapons, lots of damage in and out.
i usually go for imperial, cus its more "human" obviously, more balanced in my opinion. crap at magic, but heroic w weapons. ill usually rely on a sword and a bow wherever i go.
