I like lots of stuff... Apocalypse World, Old WoD Mage, Dogs in the Vineyard, Legend of the 5 Rings, 7th Sea...
Roleplaying is key, although I'm not adverse to a bit of dice rolling too! I like the social aspect also.
P.S. I'm quite flexible on when I can be available, but the Deep Umbra where I live operates on a GMT timezone most days.
