I didn't play FO1 or 2 but i think that a bit of humor would allow the game to be more real....
Allow me to explain:
After the bombs had drop it would have been VERY serious but now that life has gotten into a routine of post bombing I think it would freshen the game up
If done right (IMO of course), the humor is some truly bizarre stuff that should only happen out in the wastes where its bloody strange, (and who knows what's
out there these days) ~and not just simply finding some skeleton locked in a walk in meat freezer with 85 plungers , and wondering WTH!?
monty python and the holy grail?
The last time that I beat Frank Horrigan, I lobbest harshly at him the http://fallout.wikia.com/wiki/Holy_Hand_Grenade_of_Antioch.
(He was dismayed.)
