I used to write lore, quests, and the setting (places, people, things, background) for another online game I am loath to mention. I was the master of taking their old crap and tying it to the new crap, then making it not crap. I must say that some of the other writers did not like me much when I told them their writing was not up to standard. Things went bad (due to some open but not open source issues), I pulled my work, and the entire thing left me rather cautious about getting too involved in the lore of a game again.
Anyways, I guess my point is that it is not an easy job. Not everything can be 'epic', so there is a lot of boilerplate writing.
