GCM: Dark and Light is going to be a very large MMO (15,000 square miles), reportedly only using a single instance. Most other MMO's seem to find it necessary to have multiple servers in order to cut down on lag and server downtime problems. How were you able to make the game work using only one server? Will players have to worry about lag?

Stephane Quilichini: Dark and Light project was born from this idea: offer the MMORPG fan, for the first time, the opportunity to play without any border, restriction, to be totally free in his game’s universe. We developed everything in that aim: the unique world.
The server technology is based on distributed calculation in a cluster of computers, working like a supercomputer. This concept is the basis for all our designs and intends to give us the technical means to answer the ambitions we have for the game.

DnL™’s whole design is centered on this concept. It provides game masters with a great freedom of action, and players with a very special and immersive experience.

Of course, managing a unique world is a complex technical challenge, but this is on this kind of world that we can develop such a deep game design, that is rarely seen in MMORPGs nowadays. Thus, DnL™ can integrate the following aspects, among others:

a management of hot spots in fights
monster density according to player race and level
many transportation and communication means available to players
If the player experiences lag, it will be due to its Internet connection or computer capacities, not to the server.
