I'm willing to run a single-session game for any Tabletop RPG I know well, which includes D&D 3.5/5, Pathfinder, 13th Age, and most of the World of Darkness and Chronicles of Darkness games.
Obviously, if I do it virtually (the default) that'd be via something like Roll20 or over skype with maptools.
I may be willing to do something more long term if I like the group and they're happy with the results of our session!
Training & Qualifications
I've been playing these sorts of games since I was 12, and have at least a few years experience actually running them.
Availability & Preferences
Friday evenings and weekends.
