Rules Heavy vs. Rules Light
I'm working on an uber-rules light system (basically everything is based off a 2d6+Stat vs Difficulty) and am wondering if there's much demand for such a thing. The group I play D&D3.5 with seems to be a mix of thise who like to play it really loose (the DM for instance) and hardcore rules-mongers who have the PHB and DMG memorized and like to trot out the rules for "attacks of opportunity in a dark hallway vs. favored enemies on the night of a full moon" at the drop of a dime.
I much prefer just having a simple engine to handle everything, and allowing the imaginations of the players to run wild. I don't think you need a specific rule for everything. But maybe I'm wrong.
What DO you need rules for, aside from basic combat and skill checks?
