Hi! Looks like we have a few overlapping fan-interests.
I'm pushing 40 and STILL read some Young Adult books (actually, I'll go look at just about any genre if there's a story that catches my brain in just the right way XD). The most recent one to make it into my book collection was Unwind... Harry Potter has a bigger hold on my brain, though.
I was pretty big on DC until they did one timeline reboot too many (My Transformer fandom, which I'd been in since age 5, died of the same illness when Beast Machines was made), but pre-52 Batman comics are still a fave. (Oh, and Injustice, when I can get my hands on that AU). And I have a lot of older Titans issues.
Cosplay's not a thing for me, but in a way OOAKing dolls to be fandom charas IS kind of like cosplay for dolls. XD I have had the thought of turning a barbie or similar doll into Harley Quinn cross my mind a time or two. Barbie doesn't quite have the right figure, tho, with Harley in her better artwork being all petite, so that might be more likely to happen if I get another pale-skined Liv body and can swap a Barbie head on it... If I ever add her to my shelves, I'd have to make her a 'sort of Earth-3 version', so I can add the Jokester (anyone else remember Joker's good alternate?) and possibly (pre-52) Duela Dent. (The one that was Earth-3 Joker/Jokester's daughter.) But that's still a bit down the line on my doll wishlists for now.
Also, yay, Bioshock. That series was the first FPS game I ever bought or played and really the first game I'd picked up since the N64 era. Though, I have to admit - I 'played' it with cheatcodes because what I really wanted to do was wander around and look at the digital scenery. XD I have plans to sew one of my dolls a 'Little Sister' dress, second game style, as a costume.
I mostly ooak cheap playscale dolls like secondhand barbies into character dolls (My shelves currently have representatives from Final Fantasy 4, Final Fantasy 9, Harry Potter, Mega Man, Star Wars, Puppet Master, and Five Nights At Freddy's), or try to get my hands on all kinds of different 1/6 scale dolls to sew for. And since I tend to get damaged bits when I buy boxes off ebay, I also have a box of 'junk' vinyl bits that I occasionally use for weird experiments. Just so, if nothing else, people will know what NOT to do and why, because I was crazy enough to try it. XD
Anyhow, welcome! I hope you have a great time here.
