I'm thinking as the game progresses and develops a bigger, fuller community, then natural progression will lead to a full range of players that you see in everyday life, each rewarding enough for all the players... hey, a guy can dream can't he... That is if monsters become a problem, then monster slayer type of guilds will show up. If there are lots of distressed citizens in need of a Hero, then the Hero guild will have something to do, guards for hire, all sorts of guilds and job roles, etc. On the other side, this will allow Evil to do their bidding as in the long run, Good vs. Evil should be evenly matched, depending on the risks/rewards of each side. Hopefully, over time, Evil will realize that killing early level players is pointless and does not give them the reward they are seeking. There could be Epic conflicts, no longer needing the NPCs to tell a story. Course, this may not work as you can never vanquish one Evil or Good group, they just crawl out of Death Realm and back they go, no lasting consequences, or could there be... It all needs to be revolutionary and never done before in any other game. And yes, I rack my brain all the time on how to do it.
I always argue that freedom of choice and actions is always better than constricting rules. Don't let NPCs make and enforce the rules, let the community figure it out... in a perfect online world, of course. Over time good and order should win...
Good to hear some of this is in the works though. A bandit, tefu and consumer raid a few days ago? Darn wish I was around for that.
