It's much sooner than you think, and yet it will still be a little while before everything is ready.
Basically I need to complete Castle Dracula, which also means I need some playtester feedback. In addition, there is the Quest for Immortality, which is about 60% completed, and I'm not entirely sure I'm going to get the mobprogs in place before I consider it "finished enough". Likewise, I've got some crazy mobprogs in my brain that I'd like to implement in Castle Dracula, but I'd like to save them for after the 1.0 release (otherwise it may never happen).
For those of you interested in such things, I do intend to upload a copy of the final version to the usual places to find DIKU derivatives and so forth. I also plan to host a copy of the entire game here for download as well.
After this happens, I'll be looking for people to help us during the 1.1-2.0 phase of development. That's when all the big changes are probably going to happen.
