However you want to cut those definitions I'm all three, with sprinkles on the topping and extra cream on the side.
I'm into Star Wars AND Trek for example and have played various cardgames based on both those IP's as well. Next to Magic, Warhammer, a comic book collection, etc etc.
People always tell me how much I know about one certain subject and I can just switch to the next. Okay, how about Pro-Starcraft then? Yes? No? Lord of the Rings? movies in general? Monty Python? Comic Books? You know, let's talk about progressive rock. No, no, musicals! Folk? Still haven't hit a note? Westerns? Running? K-1? No, still not? Philosophy? Theology? Poetry? Acting? Singing? Oh come on, throw me a bone here. Wine? I'll do beer in a pinch, but there's more to talk about with Cognac. You want to talk about soccer? Again? Okay, I know enough to chip in here and there.
I'm so amazed when I ask people if they have a hobby and they can flat out say: "watch tv". Not a certain show or a type of movie. Nope, just work and then crash on the couch and zombie away behind the tube... That just seems so vacuous to me. Like living in that early morning dream state for the entirety of your life, unable to hold a coherent thought and just shambling around the house.
Okay, done geeking out.
