Here are a few of my favorite snobs rules...
226. You take extreem pride in the fact that no matter what level your players are they will "never" have near the amount of wealth listed in Table 5-1 of the DMG, page 145. Ten percent of this amount should be enough for any real gamer to achieve satisfaction.
227. In "your world" there is no such thing as an NPC with equipment worth near at what is indicated on Table 2-44 of the DMG. page 58. A 15th level frost giant fighter only "needs" a masterwork weapon, a loin cloth and a few barrels of ale after all. Note: All barrels of ale are to be thrown at players so they can't have them either.
228. Your players will never have enough assets to use any of the publised feats like, create wonderous items, landlord, or any others that require a certain amount of gold. After all, your fabulous story line, and magnificent in deapth style role playing should be compensation enough. Besides, only a munchkin would ever assume that he was mighty or presumtuous enough to even contemplate building a stronghold or makeing his "own" magic items. Real gamers have no preset goals for thier characters other than those approved or determined by you.
229. When questioned on any of the three previous state, that you'd rather find all new players than change the vision of your homebrew world.
