Gaming and game making are much more common though, this is a terrible analogy. Maybe you just haven't tried hard enough to find people interested in it, because you seem like the kind of person who doesn't go out of their way to find people to be friends with. It's like you've given up on the whole concept, and that's why you use the internet as a replacement.
Plus, game making can't be your ONLY interest, don't base your possible friendships solely on that one interest. Some of my best friends in the past have been people that I shared only a few similar interests with, but who I just really got along with on a personal level. Try meeting people for the sake of meeting people. Fuck, maybe you could GET someone you get along with into game making, just because you can't find anyone into it doesn't mean giving up forever.
Pretty much this. I was the same way when I was, like, fourteen, but you learn to get over it and (usually) appreciate the merits of interacting with and becoming closer to other people. If you're really that fixated on GAMING/ANIME/MOVIES (or whatever) just wait until you get to college maybe? I think a lot of people tend to discard the silly stigma they have for talking about "socially unacceptable," things when they get out of high school and are allowed to be themselves.
I know your entire argument is essentially "why do other things when I don't want to?" but I feel like that's pretty nonsense logic. Why go to school, worry about your hygiene, or take care of yourself? Why even get up in the morning? =/
