If the version is not listed, I have not played it. This is limited to the PHB/DMG/MM1-2 of each, as I only ran the games this way. Too many rules supplements ruin games, imo. I've been like that since I started gaming when I was 12. For example, I only used the equipment from the 2e thieves book. No prestige classes allowed in any game I ran.
#1: 2e. I played and DM'd so many games of this I had the base 3 books basically memorized. I loved the NWP system and specialized clerics and mages. The settings were amazing, as well. This was the high point of creativity of TSR, imo.
#2: 3e/3.5e. Solid rules. Too complicated, but things like ascending AC and the saving throws were major improvements over the old systems.
#3: B/X with Otus covers. The first version of D&D I ever played. I had a lot of fun with this game.
#4: BECMI. I really just added the Companion and Master sets to my B/X books.
#5: 1e. It was fun, but convoluted and had many weird limitations that are luckily now gone.
#6: 4e. Tried it, didn't care for it. We played two sessions. It felt more like the Descent boardgame than D&D. I can see why new players would like it, but it's not for me.
