Brook m. said: As a child I played the 1st Edition (4th version) and had the Basic Set (red box) Expert Set (blue box) Companion Master sets (teal box) Master Set (black box).....but rather than hunting those back down, or do most player now play 2nd, 3rd, or 4th edition? Hey Brook, welcome back! In rough order of popularity, it goes Pathfinder, 4th, 3.5, 1E and 2E. However, WotC is going to be releasing 5th edition or "D&D Next" most likely around GenCon of next year and you can download a playtest packet or preview from their website. There's a thriving community around the playtest packets as well. That being said, if you're coming in and DMing you'll have no problem finding players for whatever edition you choose. I run a Swords & Wizardry game (a retroclone based on 0E original D&D) which had no problems finding a solid group. If you're coming back just to play, then you might need to take whatever you find available first and worry about the details later. There's a pretty sharp lack of D&D DMs and a common complaint is not being able to find a spot in a game. Either way, good luck!
