AD&D player here, grew up on the system and it wasn't until recent few years I started into 3.5e and Pathfinder is a recent (like, last month) pick up. Granted, when I picked up the game, I was like, 13, so some rules were pretty hard for me to learn and I homebrewed A LOT to keep flow (cause I had the books so I was the DM, XD). Luckily, I roped my friends into trying it, and we've been playing for about 7 years now. Only reason I got into it is cause my dad had the book sfrom his youth when AD&D was still relatively new.
I still remember that first game, Zanzer Tem's Dungeon. So much fun.
Anyways, I guess I'd be down for games using the old AD&D, it's been a bit though so my rules are probably all jambled from different versions now, XD. So yah, hit me up with a PM if your looking for a player.
