Played it for years, started in 1979. Played 1e AD&D and the Basic version pretty regularly until 1985 or so. Sporadically after that (I discovered Traveller, Dragonquest, Rolemaster, and eventually GURPS, and played those a lot). I played a little 2e in the 90s, but not much. A lot of 3e/3.5e since they came out.
I played and DM'd D&D and AD&D starting in late 1981 (age 11). Moved to 2e briefly (we didnt care much for it), moved back to 1e, then switched to 3.x when it came out.
Yep. I started with Holmes and almost immediately started mixing in AD&D. As I discovered new rules I'd never noticed, or things I was doing differently, I added them in, and eventually I was running (mostly) by-the-book AD&D.
I began playing in 1982 as an AD&D DM. Still DM a 3.5 homebrew game today that includes two players who started playing the same day I did-as two of the first three PC's in my campaign. I have rarely had the chance to run a PC (just a few one-shot adventures and in two campaigns that lasted less than 3 months each), and all but one of those were 1st Edition. None of the other players have the time or dedication to run a campaign.
I started with the Moldvay Basic Set in 1982 and then moved to AD&D (both via my older brother's books).
I stopped gaming about a year after second edition came out -- 1991... maybe later. I'm not sure, but I know I had the first Ravenloft and Spelljammer boxed sets and several reams of Monstrous Compendiums.
