I haven't played Fallout New Vegas yet (I bought it 2 years ago), but Fallout 3 was wonderful. As long as they keep to the same quality, I'd be happy for anyone to create a new fallout game (as long as it's plot driven).
Basically just take my money
I can explain the one about shoot and turns to dust, but their clothes are still in tact - the wasteland is a really dry place, and there's not enough lotion to go around. Ergo, their clothes remain while their dry skin decomposes.
Extremely thorough, makes me feel bad that I never got past the first quest (getting that special part from that other vault - couldn't figure out how to descend down the elevator).
