The old D&D was sweet, before AD&D. the newest rules though , what are they on, 3rd edition? just took a lot of the fun outta it for me. As "nerdy" as everyone thinks it is, there are a lot of non-nerds that enjoy. its an awesome social game, and almost nobody who's willing to try it doesn't like it. Though most are afraid to admit it, there are more people playing it than youd imagine. Go to a game shop and ask around. dont be embarrased, nobody at a game or rpg shop has any right to make fun of you... everyones prolly a geek there
Anyway, good luck and have fun. i reccommend starting on the older 2nd edition rules and modules. you could problably find the games, and resources used for very cheap. this way if ya DONT like it, you havn't had to sell your house to afford it, since all the various books and modules and dice can get expensive after a while.
