That's what keeps bothering me. I hate not knowing what's out there.
I generally subscribe to the same thing. Discovery is my bread and butter. But whereas i am likely to be dead and gone long before Science finds the secrets of the universe, too much descovery mutes the ability to further expand on a story. Take Warcraft for instance. The act of discovering new lands and people died with WoW. In Warcraft 1, 2 and 3 you could find strange creatures lurking in the woods and be lie "WTF is that thing?". With WoW, they opened the whole world. Suddenly you could see everything, right down the some little shanty with a crazy necromancer in the woods. The thrill of descovery wore off quickly, and has never really been recpatured. Then they have to go and Retcon things to try to rebuild it, like Pandaria being a whole contenant rather than a secluded nation in Kalimdor.
Retcon's are bad. I would rather not know, then have to deal with what i know changing because they railroaded themselves into a corner.
