Well my objectives are these:

A Massive game, with 3000 players, with pay subscription so i can hire servers, and free updates to the game. All the game packet will include models, textures, sounds, and everything that can be used to avoid band consuming.

The server will just take care of , Player names ( created when player registered online), last position, skills, movement information, character extras.., assets, chat.

Its a space game, i don't know what the 1 per zone meant. Since there are alot of solar systems, there is just one server, i think there is no need for more.
Everything will be loaded when you enter a different solar system.

Right now everything is goin okay.
