Peering at the sands of time...i think that the first one i played was B3 Palace of the Silver Princess (i remember that first session fondly, but B3 is not one of my favourite modules ), it was 1983. The first module i bought and ran, was FRC2 Curse of the Azure Bonds, in 1989, it was fun to ran that first module with my friends, it set the base for 10 years of playing AD&D... Then a 15 year pause until LMOP
