Yeah I dropped some change on PDFs tonight. Like 12 of them: AD&D 1st ED MM as well as original FR Boxed set, and some AD&D 2nd ED bits too. Fiend Folio, Unearthed Arcana, etc.
I can't find the actual books anywhere (I had several but they vanished).
Over time I'll be re-collecting them. Likely head down to Chicago and Games Plus soon and see what I can find.
Until then I have reference materials. I have some ideas in my head too. I started on a basic world map tonight. Lets see where this takes us!
