Perhaps it would be convenient to create one or two backgrounds and throw together a small demoversion of one of the game's scenes (in Flash, AGS, Wintermute or some other existing engine)? I think the full game should be done in our own engine, but if we have nothing to show for a long time, we may be forgotten (the mention of our project has already been deleted from Wikipedia).
i know that we will be forgotten if we cannot show progress but i would rather not show progress for a year , then just show some cheap work in progress (not even in our own engine) created material. there will be material when its done.
actually some work in progress showing art (background, animations) and two screens or so done in flash and integrated in the homepage would be a great teaser, also for finding team members. of course the art for these two (or so) screens should be high quality
