Lazy Saturday post

Today's two fandom meme questions are so outside of my general approach to fandom that I've been staring at them for quite a while and wondering how to answer them (although I had an amused moment contemplating the idea of the Peaky Blinders characters as contestants on Bake Off). But it's hot, and I'm tired, so I'm going to be lazy, and throw things over to you.

Instead of answering the questions, I'm going to pose one of my own: for those of you who enjoy crossovers, fusions, and setting change AUs, what it is that appeals about them? I always love to hear about other people's different approaches to fandom, and different tastes when it comes to fanworks.
