We will let you know more in-depth about this project after Christmas, after we get content together on our side.
It's actually a game developed in tandem for PC, while DCEdge will not be released publicly, our project will. Once we get stuff collected we'll post more details. Right now we're just tweaking DCEdge for the project, once our main server comes back online we'll launch our site for it as well. Want to give you guys the full scoop, we hate tidbits. Unless you guys asked for them (hint, your IRC channel is a good start). It's a pretty exciting project, been hard for Chui and myself to keep hidden.
While, I should note, it is
based upon the Doom engine, it plays nothing like it.
In short, if you are confused, DCEdge is the engine the Dreamcast title is running on, because it shares the similar engine for PC as well. Dreamplaces is much the same way.
