I will hopefully soon be running AD&D 2nd Edition for my Monday night group, which is currently making its way through the Serpent’s Skull Pathfinder AP. After running 3.x and Pathfinder since 2000, it will really make a nice change :-).
We will be playing with the class/race splat books, and a lot of the optional rules, as I like crunch. There are some options not available, like Bladesingers and Elven archery.
I plan to run the party through several first and second edition modules I own, cumulating in G1-3/D1-3. They will start with N1: Against the Cult of the Reptile God. Along the way, I hope to run Castles Forlorn, House of Strahd and the Dungeonland modules, as well as a couple of the UK modules. There is also the option of Greyhawk Ruins to fill in gaps.
