Most Original adventure?

[johnsemlak]

I'll agree with others that this question seems rather open-ended.

Are we talking most original all time? Just in the 3e era?

For, me it would have to be GDQ - let's see what new concepts were introducted in that campaign...

drow
underdark (called underworld in those days)
battling/killing demon lords

plus stuff mentioned above in the Q1 module

Of course, it all seems so cliche nowadays...

The Midnight campaign setting. Everything else is fighting for a distant second place.
