3.5 homebrew, why?

[Gnorman]

Seerow, I believe he also likes to get blotto.

On a serious note: as a DM I allow homebrew because 90% of the time it will allow my players the chance to experiment with new mechanics, express their creativity in new ways, or just plain have more fun. Yes, there are limits and all homebrew should require scrutiny, but I always offer my players the opportunity to run it by me first, and if necessary, reach a compromise rather than have one (or both) of us be unhappy at the table. It does make for extra work, but I consider that time to study and evaluate the result of another person's creative process - enlightening and inspirational at best, curious and amusing at worst.

Adherence to rules simply because they were printed that way is unnecessary and potentially harmful, I think. Every table is different. Sacred cows need to be slaughtered now and then.

Granted, I am heavily biased - designing the game is more fun for me than actually playing it.
