An unseemly amount of money has been spent by me on modules and adventure paths over my hobby lifetime. At one time I have owned practically everyting that TSR released for 1e; about half of all basic D&D modules; a Hell of a lot of Dungeon Magazine; and held a Pathfinder Adventure Path description for over a year.the number is probably just north of 100 modules & adventures and that's only counting D&D. It is why I was always kind of mystified at the whole "adventures dont sell" mantra in the 2000s - I was one of the perpetual suckers.
