My most frequent role in my gaming groups is the GM. It's been like that pretty much since I started gaming back around 1980 / 81.
The times I was a player, it was rarely AD&D. For some reason, others would run Rifts or Battlelords or whatever, but AD&D was my realm to run. No one else wanted to step up, and most of what we played was AD&D.
My last AD&D session was at Gencon, back in 1993 or so.
Tonight, +Joe D is running G1 for our group and I'll be using one of the pregens from the back of the module, and I'm going to game like it's 1993 again.
