Me - late 30's, Roleplayer, live in Cambridge with family.
Been playing RPGs (AD&D, Traveller, etc) since about age 10 but had a big break from them over several years as real life got in the way. Now play in a regular weekly game with a great group, also Collect DDMs (and a few Star Wars and other SF pre-painted minis) for RPG use only.
RPG wise currently playing Mage the Ascension (using the old revised rules set) and prior to that D&D 3.5 and Pathfinder - using the Dark Sun and Dragonlance settings.
No plans to go to 4e (WOTC have 'fired' me as a customer I fear).
As a group we also play, have played recently, or plan to play Call of Cthulhu, Traveller, WFRP, AD&D 1e, Basic D&D, 3:16 Carnage Amongst the Stars, and Primetime Adventures.
When we can't get everybody round the table for RPGs we also play Munchkin and/or Magic from time to time.
