If there's one regret i have with Morrowind and Oblivion, it's that i never took the time to learn how to use the Editor. Generally speaking, i can find mods that "just about" fit my ideas on what kind of rpg Morrowind could (and Oblivion
should) have been, but either they clash with other mods i already use, introduce too many changes that i don't want, or just fall too short of the mark. If i had the time to learn, i'd have the means to customise my own rpg out of the one that comes closest to my liking. But i don't.
I think many people fall into the same category.
