Everquest Next promisses a lot, but can it delivery?
I see 2 options. Either they go Molyneaux and simply don't delivery what's promissed, with the features greatly diminished, or they DO delivery, and the players will turn Everquest Next into a virtual wastelands littered with phalus effigies.
Penis monuments aside, a world where the players can really shape it is interesting, if they manage to keep the griefing to manageable levels. I'd play it if only to see how it would develop. Some stuff like NPC killing can be prevented (to a degree) with stronger NPCs and bounties but players are a crafty bunch and for every measure they will try to find a counter-measure.
I'm honestly interested in Everquest Next, IF they manage to pull half of what they are promissing.
