The Difficulties Engendered by Equation #3 Concluded, or, Not Done Completed

No system, and especially none so complicated as a decent Mud, is complete unless and until there is nothing left to remove.

Take any Mud of your choice. WoW, LotRO, GW, APB, SW:ToR, etc., and look at any feature of that Mud. Now pluck at that feature and draw it completely out of the Mud. If the Mud survives, then that feature was superfluous. It should not have been there in the first place and was a distraction. It was more than a distraction. It also caused considerable harm to the Mud. How was harm done by such an innocuous thing? Consider that time, money, energy, and so forth were expended on designing and implementing that feature. Those resources could have been spent elsewhere. They certainly should have been spent elsewhere. It certainly would have been better were they expended elsewhere.

It would be trivial to add email capability to your Mud. But what purpose would email serve? What requirement of your design could only be served by the addition of email? If you can't come up with an answer, then simply do not add it in the first place. Focus your energies on those areas that actually align with your design!

Failure to abide by this rule results in a ``kitchen sink'' mindset which is incapable of producing naught but nuts & gum abominations.
