>>46805515I'm someone who's also interested in the psychology of things. One of my favorite pasttimes is simply deconstructing things and putting them back together. Getting down to the bottom why people like a given thing to understand its true appeal. Passions and hobbies don't come out of thin air, you need to look into why someone would become obsessed with it.
Lemme give an example of such a case through some armchair psychology. Most autists like myself are big into trains. I didn't understand that for a long time (always been a fagg/o/t myself), and then that "aha" moment hit me.
Autistic people don't like change, we downright hate it because we're so used to routines that a minor change can completely throw us for a loop. Trains work similarily. They're tied down to a given track, going about the same routes day in and day out, the same schedule down to the minute, all with little change. If there is a change, or a new route, it's treated as a big thing. Trains work on monotony, doing the same thing for years on end, and autists can relate to that in a way. We're fine doing the same routines on loop (we're the perfect wageslaves), because we're familiar with it, and we feel safe because it's predictable, what we know.
As for your main post (got carried away again, sorry.), that actually makes more sense than what I was getting at, really. It broadens horizons, opens doors to hundreds, if not thousands of new ideas. Just the notion of the crossover is enough to make people have that "aha" moment. That's why a lot of fanfiction pieces online tend to be crossovers. That "what if" mentality leaves the door wide open to so many different possibilities that literally anyone can imagine.
