As I'm already running a game every other week and am no longer young and bored enough to run two campaigns at once, I'm planning to run roughly once every two months. The campaign is made up of one-shot sessions, so except in extreme circumstances, I won't need specific people to attend to make it work, so if you can't make the first one, you can always join in later sessions, and vice versa.
The game is a systemless one - it won't be completely diceless, but it'll be up to me as to what needs a roll, and I'm likely to be inconsistent.
The settings will be historical. The first game was set in 1268, in Jaffa, Israel, and the other sessions will be set in different years, eras and locations. As above, characters will most likely not persist from session to session - players will arrive, pick a pre-generated character, maybe make a few customisations if I come up with a system I like, and we'll get started, saving on gen time and giving us more time for the game itself. I'll try and make more pregens for each session than players, so that everybody gets a choice.
I'd suggest the weeks ending October 10th and October 24th as a good time to have the first session, so if anybody is interested, let me know what times on those weeks are good times for you, and I'll coalesce some dates to pick from.
I hope that's piqued your interest! If you have any questions, comment here or send me and email, and I'll get back to you.
