Will the server program be released to anyone for free?
If you take a look at the downloads page, you\'ll see a CVS thing, which includes the server (I think, but it\'s better you ask the devs tho. I\'m not really familiar with the Linux version.)
Will there be a toolset to build worlds?
Crystal-Space. But you can only build your own worlds if you use your own server, graphics, NPCs, quests and weapons, cause they\'re copyrighted.
Will there be the possibility to connect to a ODBC database for world persistence?
Suppose only if you run an official server. Dunno tho. Ask a dev.
Will the game be programmed so that \"modpaks\" will be
easy to implement?
There will probably be no \"modpaks\" from players on the official. You can \"modpak\" your own server as much as you want tho.
