When will there be more news about the combat prototype? I don't know much about it, except when you talked about it on the server. And will there be a separate download for this? Or will it come with the normal game?
The combat prototype is on hold while I get some other stuff working. With a working AI and object scripting system, motivated scripters could essentially implement basic combat and other things in the standard point-and-click RPG style... probably long before I've finished the real combat (if they were so motivated). And AI is important for other reasons anyway so I will get at least a prototype of that working first.
There will probably be a publicly released separate combat prototype before it is incorporated into the main game. It lets me try things out in a smaller setting. Though, if full physics makes it into the main engine first then there is no reason to hold back really.
Another question would be, is the Main server going to always be Build? And will there be another Main Server (Hosted by you) for Game Mode, or Combat Prototype?
The current public server will always be a build server. Too much has been built there to properly support an RPG game. I will set up a second server when the RPG game elements are far enough along. By then that may require registered accounts, though (ie: people who have donated). The current server is planned to remain free.
