Tough call but had to vote for the
PHB over
DMG. Though the
DMG is a wonderful thing and I find something new or newly-understood every time I dig into it, the
PHB is the core of the game for me.
Part of it has to be that for the first six months or so of my AD&D career, a
PHB was all we had. I was voluntold to be the
DM after our first session with an experienced AD&Der and basically made up my own monsters and combat system based on the things mentioned in the
PHB. It was a wild ride and I constantly try to get back to that.
The Players Handbook is my "desert island" gaming item, so it has to get my vote in a poll of favorites.
