>>25225997High-functioning Aspergers sufferer reporting in. While the diagnosis is different for everybody, I personally find games with complex and/or hard-to-master rulesets very fascinating. Chess, Go, Civilization, MTG, WH40k - you name it and I've learned it and probably gotten damn good at it too.
Hence I'm naturally drawn to competitive Pokemon. I've done quite okay for myself on Showdown, and logged far too many hours EV training and learning to Inject. I would imagine that this is the case for a great many autistic / aspie Pokemon fans out there.
Now, if you have any kind of creative talent, then you're likely going to want to use that talent to create works of art related to your interests. Vouching for my personal experience as a writer, I've written some damn detailed "Create-a-Gym" and "Create-an-Evil-Team" vignettes for /vp/. If I could draw then I'd probably draw some cool artwork; Scythers fencing with Bisharps or some shit.
And while I can only conjecture from personal experience, I highly suspect that if I was lower down on the Autism Spectrum - closer the the Christian Weston Chandlers of the world - I'd use my talents for Swalot Vore pics or Gardevoir Rape fanfics. Thank god I'm not.
