Less rules... hm, the basic d20 rules-set seems ok (leaving out problems w magic system) for PCs; there's a problem w NPCs though, as evidenced by the "Imp w +4 bluff" thread recently. I find therules-bound nature of the game makes GMing more work & less fun for story-based, world-simulation or narrativist approaches. It can make combat as a skirmish minis game more exciting, but within very tight parameters of what is an 'acceptable' combat, eg the "no more than 12 enemies" rule, which gets ridiculous w high-level PCs.
