Currently, I'm running both Castles & Crusades and Lejendary Adventure. Also, I played my first session in years, the other day (I usually DM), and that was in classic D&D (BECMI version) -- it was a lot of fun. I played a Dwarf.
I have a True20 mini-series (6 sessions) queued up for some time in the future. We have a 3.0 game (in Rappan Athuk) which is in stasis, at the moment, and an Arcana Unearthed game that has shifted to the back burner, too.
