I play tabletop roleplaying games, specifically GURPS and Dungeons & Dragons (D20 and before, I'm not into 4th edition D&D). I have always been a bit of a recluse, and loved science fiction and fantasy. RPGs allowed me an excuse to seek out others and interact with them. I've made a lot of good friends playing these games. Hell, it was RPGs that caused me to meet the woman who became my wife.
I just wish I had a group here in Melbourne. Yesterday, my wife mentioned she missed gaming, too.
