i started DnD right when 3e came out and was hooked. before that it was MtG all the way until the summer of '10, where i got fed up and sold as many cards as i could
i have looked through old 2e/1e stuff just for the information on outer planes and deities and stuff.
tried 4e once and came back.
am kind of interested in some of the PF stuff... but haven't gotten a chance to read much
