Most of the original Fallout's "dark humor" was added just to make co-creator Tim Cain laugh: "We made this game for each other. When it shipped, we were like, 'Well, I hope other people like it!'"

It turns out all it takes to make one of the most influential RPGs of all time is a team of developers who just want to make each other laugh.

That was my takeaway from a recent Game Informer interview with original Fallout co-creators Tim Cain and Leonard Boyarsky, as well as Interplay co-founder Brian Fargo.
