Wow fastlane, I never knew there were books around on MMORPG design ^^
1 per zone? what you mean?
Well, by MMORPG I am guessing more than 10 players (the massive part). You cannot possibly have the thousands of players that a MMORPG has, all contacting the one server...
Imagine a whole world, all with one server?
You must sub divide the world into parts, one server controlling one section or zone. Then when a player moves in and out of one, pass the information to the next server to process. Of course, its obviously much more complicated than this ^^
Getting 8 players to work smoothly is hard enough
Thanks,
