Rather than split up the same world be split into 3 simultaneous versions, why not split it along different lines? Why not have different realms/continents/etc set up on different servers?
Ex:
Let's say we have the current GW world set up. Let's stick Tyria on one server(persistent rather than in its current form), Cantha on another, and Elona on the last. To be able to travel through the docks to another continent you have to be able to reach a certain point (the docks) and afterwards you can always just hit the map travel button to get to the boat. If they really wanted to they could require ascension or something before server/continent switch was allowed.
The reason this seems like a good way to do it is this: a large complaint/problem/whatever with a multiple copy persistent world is playing with all the same people and not having to choose a server to be able to play with certain friends. Each 'realm' would be its own persistent world, and each continent would be no more divided than currently.
If you want to add another continent/ realm, simply attach it to another continent which doesn't fully use its server or put it on a new server(so you can independently test it before release). Putting it on a new server means you only have to worry about integrating it on the docks with options, rather than uploading a huge download for the entire continent.
Now I understand this would probably up the traffic between servers (don't know how that would affect the game), but why not do it this way rather than have the multiple worlds? In my mind it would be an interesting way to get away from one of the downsides of a persistent world. As a game grew, you would eventually need more copies of a server, but it would up the population limit involved in each copy, so it would only work up to a certain level (I suppose).
What do you guys think?
Oh, and if this hadn't been thought of before, I hereby claim it as my intellectual property(
But that's just my two cents
