I played (the Original version mentioned by Slayton) for years in a club throughout and after college.
Our (permanent) Dungeon Master even wrote a book on the game!
(His GF played, too, and they had a D&D-themed Druidic wedding a couple years out of college! It was a blast! Most everyone came in character, which left me walking on my knees all night! [My character was a dwarf!])
I still have my die box... somewhere!
Anyway, being in the "computer graphics industry" i always dreamed of playing the game by computer and skipping all the out-of-band stuff like die rolls....
WoW looked like it might come close, but it wasn't for me. (Too many brats, and I won't pay-to-play anything on subscription!)
I recently (like, 10 months ago now??) found an MMORPG like WoW, but free - completely - and have been playing that for hours a day now. (Instead of Halo Race, if you haven't noticed....
)
[FYI: It's rated "Mature" and you must be 17 or older to join and play....]It's not D&D, but it's close enough for me!
