I for one would be thrilled if much more MMOs used this type of server idea in their system. Especially the more infamous ones like WoW, Star Wars Galaxies, Ultima Online, and others that have seen significant changes from launch to present. There's usually a vocal community for these and other games desiring to play the game it originally was and I support that.

There's always the possibility for increased marketability with this too. The regular players can keep on doing what they're doing, and the older, more devoted players can revisit the style they know and love if they desire. Nobody loses, it caters to all fans of the game, and lowers the possibility of private servers taking away from profits.

Here's hoping Mythic follows through, and it inspires others to follow.
