Gamers like dragons. Gamers like boobs. Gamers get dragons with boobs.

Doesn't take much more thinking than that.
A lot of it is just that the average person has an easier time relating to similar things than to unusual things. Sure, some of us get a kick out of the extremely unusual, but most people just want to apply the spiffy aspects of other things to what they're otherwise comfortable with.
