My game group here meets once per week, we play 2 HackMaster 4th Ed games. We alternate weeks so each game is played every other week. I also play in a weekly HackMaster Basic game. In the last year I've played in a couple of Mongoose Traveller games at conventions.
How is Leverage? I am somewhat familiar with the cortex system (I have played Firefly and read over the revised "Cortex" rules. I also am a fan of the show,to be fair I checked it out because I had heard of the rpg.
I clicked "OD&D," because (pre-1st edition AD&D) Dungeons & Dragons isn't broken down on the list. I've been playing the Moldvay/Cook "B/X" version of D&D.
I've also been playing my own permutation of Microlite20 lately.
