I'm sorry, but the idea that 2nd edition can be considered "old school" still blows my mind. That the Planescape and Ravenloft games I played in during the 90s could be characterized as "old school" is just plain weird given how radically different they felt from the D&D I had been playing in the 80s.If we're going to draw a single line in the sand of Old School vs New School, I think the 3e release (or WotC purchase) has to be it.
thats a bizarre definition, there was plenty of protagnists, epic adventure and "story" in temple of elemental evil or temple of doom.
I mean to say tomb of horrorsWell, yeah, Temple of Elemental Evil (1985!) is definitely either very late old-school and proto-trad, or it's fully post-old-school and therefore early trad. (I'm inclined to think the latter, because of the assumption that the PCs are heroes out to defeat Evil rather than just tomb-robbers who want to loot the Temple by happenstance.)
But… what do you mean by "temple of doom"?
