Lately me and some of my real world friends have been playing oGame, which is sort of like an online version of the old Masters of Orion 4x gaming genre.
In that kind of game you colonise worlds, build up the colony's infrastructures and manufacturing, research new technologies, build fleets and carve out your own little galactic empire by force or by trade, while hopefully managing diplomacy with friends and foe to keep yourself on top. At early stages things take place over matter of minutes but later on actions can take hours to execute so it doesn't tend to reward time spent sat at the keyboard grinding but rather long term decisive actions.
Given the nature of the game, I figured that it'd be a natural choice for folks on the spectrum seeing how it rewards tactical, patient, logical thinking over twitch reflexes and angry onslaughts like most online games.
Anyway, if any of you guys decide to try it out, sign up for Universe 22, which is where me and my friends play, and either send a mesage to Ryuujin or go to the "Alliance" page and send a request to join Pwn3d, or just post your galaxy/sector/planet in this thread, and we can hook up. (And I might be able to send some resources to kickstart your empire)
If enough people get intrested I think we should form an all-spectrum Alliance and show the Universe who owns their *** ^-^
