A few weeks ago I started running a Mongoose 2nd Edition Traveller game on Roll20. It's set in 1105, in Reft Sector, in the Islands cluster, and involves the players locating and trying to recover a ship left behind by a failed Imperium intelligence mission. I'm putting some background notes and various resources on this site for future reference and general use.
Sessions are being blogged about on a weekly basis.
I'm also playing in a Zweihänder game.
