all infomation will be stored on the sever so i dont know what ur meaning by connecting to a database

ok, this is a mmorpg

I was thinking in the nwn model where you have:

a standalone server
a player client
a dm client
a world builder tool

there are hundreds of server (each one with a max of a hundred players), you can run your own server and run the world you have built with the world builder tool, and you can dm your world for your friends. In this model, the database has sense because some of the servers are not 24h/7 and because world buiding is not catched on the fly, and you have to restart the server.

ALthough very far from this model, planeshift seems to be a very very cool game!.

By the way, do you know a totally open source proyect of nwn-nature?
