Place to keep houserules if (re)start another DnD 3.5 campaign:
Guidelines:
KISS = Keep it simple, stupid. The more esoteric the rules, the more players' eyes will glaze over and the DM will have difficulty keeping the game going.
Compatibility. Especially with published materials. Do you really want to go through ever NPC in, for example, Ptolus or the city of Sharn to make sure all fighters have a feat per level plus can wield stances/maneuvers from ToB: Bo9S? Or, worse, every NPC sorcerer/wizard is customized per the mish-mosh mix from UA? And let's don't even get started with monsters...!
