I will list all of the things, because why not? At least, all of the things I've played. I've sat in chargen with other characters for ages but never got around to doing anything. See: HM
Active (for varying degrees of 'active')
City of Hope Salimah, Natalya, XP Mule #10372
Exalted: Tales of the Dreaming Sea Viridian Serdio
Fallcoast Deborah Wagner, Juliette Skinner
Fallen World Pluto, Cassandra
Shadowrun: Denver - Deborah
I list the active ones based on the ones I currently log into and sit around/do nothing on/occasionally throw myself into scenes when the mood hits.
Star Wars: Age of Alliances - Lynn Rathan, Bana Cynis, Jipp Kunno, Vosa'niru
Star Wars: Old Republic - I forget the name, but it was a prototype droid sent out on his own so he could install upgrades the corporation would never think to add on their own
HM - Many people who never made it beyond chargen
NYC - (Clarifying which NYC, it was the one where Mages caused 9/11. With a spell. And mortals just hallucinated planes. Then staff changed their mind and made it a different building, because they couldn't figure out why this offended people.) Felicia, Pyrrha, Yvette
The Reach - Danica (both the mortal and the vampire-ghost-bloodline-thing), Jean (Reed Werewolf with an unnatural Duck obsession)
Exalted: Fire and Glass - Arsinoe, Heavenly Pomegranite, CynisViridian
Exalted: Where Rivers Meet - Arsinoe, Grayle
Exalted: Gunstar - Hotaru
SerenityMU - Genevieve
KishiKaisei - Setsuna
In case it's not obvious, my RP preferences are all over the map.
Oh shit. I failed to mention that iteration of NYC, and I staffed there.
Man, I never got around to apping in any of the Exalted MUs. I didn't even know there were more than two.
Updated, for lolz.
