The less-polished more-enthusiast feel of most publications.
Strangely enough, the more professional it looks, the less soul it seems to have.
And that applies to any RPG.
Iron Maiden's Piece of Mind is the album to means D&D the most to me.
Lots of Malmsteen, AC/DC and early Def Lepard get put into that mix for when I started.
I have diversified quite a bit since then, but still love those bands.
Conan the Barbarian
Highlanders (Braveheart Scots)
Islamic medieval
Japanese medieval
Indian medieval
North American Plains indians
African/Zulu tribal
Aztec/Mesoamerican
Vikings
Romans (1st century AD, like Gladiator)
Ancient Greeks
Greeks in leather speedos/Pierced...
Though the adventure was simple, we had a blast. Smart playing held out against bad rolls, and except for the crit to gavin for 34hp by a bugbear, minimal injuries for the most part.
I love those little character treasure boxes. Pure goofy genius. :D
I would like to add that if (as an example) your party only explored 3 rooms in 6 hours due to size, but everyone had fun, what's the problem?
We have had games like that and I remember them just as fondly as plot-heavy ones.
