Victoria Rules
We-ell, my three houseruled-into-oblivion 1e campaigns lasted 10 years, 11.5 years, and gawd-only-knows-how-many years (2.5 so far and just nicely rounding into form); if that's not long enough to meet standard please let me know.Balance is to keep the game flowing in a clear direction. As much as I like AD&D, it's lack of clear guidelines on treasure and experience lead to the famous Monty Haul sessions or players being of vastly varying power. If you ignore the rules then your game will fall apart. That last statement is based on personal experience but I have yet to play a single D&D game where more than a handful of house rules didn't turn into an absolute mess.
The number of games that go from level 1 to 30 is disproportionately less than games that end after a few levels. This could be attributed to a number of reasons but I can guarantee you that people who rewrite the game find their campaigns ending a lot sooner than those that don't.

I've come to believe that if we treat the rules in one extremely key way then our games will be better for it: that all involved play by the spirit of the rules rather than the letter.
If you're a player who is always looking for the loophole or the broken combo then sure, you'll almost certainly find it. But in doing so, you've just made the game a little less fun than it was. So don't.
