old school modules. I dont like the big adventure books. I want 20 pages good quality (kinda likea good magazine) with detached/detachable maps and tables. I dont want to buy the books cuase i know my group will send me all kinds of sideways, but the biggest resource i love from them are the area and dungeon maps and things like random item tables. I tried running a ad&d campain in highschool(couldnt get players, using books my dad and uncle gave me) and i spent hours and had fun going through a few of their odl modules and just thinking about things i could do with those resources and bascallly ignoring the story stuff in it
