Hi arslayer!
We stopped playing D&D back in 1989 and RPGs in 1994, due to "life" (studies, careers, kids etc). I started playing in -81 or -82 with Moldway/Cook B/X and after some time we went on to AD&D, but like you I had my best experiences with B/X D&D.
After stumbling over the OSR sites like Dragonsfoot and various old school D&D blogs I managed to gather most of our old D&D gang and after something like 6 months of lobbying we played our first D&D session (using Rules Cyclopedia D&D) in march 2011. That's after a 22 year hiatus! And now we play about once or twice a month, 6-9hrs/session.
I also introduced my 9 year old son using a Swedish version of Mentzer BEC(MI) D&D and we're planning to run an adventure for some of his friends too
At the moment we're playing Call of Cthulhu (a campaign we never finished back in 1994), and coming up is a Pathfinder campaign by one of the players (yes - I get to be a player!!)
And my forthcoming project will be a Labyrinth Lord (+ AEC) campaign set in the World Between (Tales of the Grotesque and Dungeonesque).
The fun thing is that some of our wives and kids are now showing interest in RPG:ing, so there's a lot of opportunities for gaming!
Long post, I know, but here's another long-absent gamer back on track
Good luck with your gaming!
