Same. I've always been that way too, it's why I latched onto RPGs so early and so hard in my gaming career. I have never been satisfied with just being told, "okay you have to do this" in a game. I need motivation. I need a reason why I'm killing the dragon for loot, and it has to make sense and be compelling, or else I don't give a monkey's arse about killing the dragon, it doesn't matter how fun the technical act of beating on the dragon is.

Which is why I've been pretty distressed to realize that the only way I can remain engaged in WoW anymore is by completely ignoring about 80% of the current story and pretending like my headcanon is the way things are. It depresses the crap out of me, but I've been so disenchanted with the way the story in this 'verse has played out since BC and the directions it's been drifting in during Cataclysm that the only way I can keep myself engaged in the actual gameplay aspect is to ignore most of the story. Even liking my guild and my raid team as much as I do. (As it is, I really only log on for raids/prep anymore. Because Ragnaros is utterly boring as a villain to me, heh.)

It's starting to remind me of Star Wars. You know that old affectionate joke about having to hate Star Wars in order to love it? I'm nearly at that point with WoW.
