There has been some discussion on this in this thread
some time ago. Look for my second response to see my view on it, indeed some kind of Ogre themed minigame.
Let me quote what Sinbad said in that thread, replace toolchain with demo(game):
Guys, I don't think anyone disagrees that a slicker, artist-oriented toolchain is needed.[...] What we need is less people asking, and more people doing.[...] Less talk, more action.
So let's get this thing started, damnit! Is there some place on it's own to discuss this and start organiszing? Maybe somewhere on the wiki?
The way i see it now, is that there are two routes that would work very well for some extended demo, not as alternatives, but both adressing different things:
one is such a mini game, a community effort in programming, design and art. This would be a complete game, which is manageble since it could be level based, with one or two levels for starters, or some dynamic level creation.
The second would be a series of tech demo's, but much more evolved ones then the current, showing every aspect of a given feature. These would have all options that apply to that feature, trough some well designed and consistent gui. In this i think debug visualisation of what is happening is also a big plus. So these demo's could be standalone, or come together trough some browser
The game demo would be one big show off, concentrating a lot on art. I know, this is a programmers community mainly, but with ogre getting lot's of attention, i'm sure we can attract people from other communities like cgTalk, and there are many creative programmers, or programming artists here. let's face it, all the tech only really shows with great art, this is the selling point and differentiation of games nowadays. So this game would be more targeted at artists and game designers, showing ogre in it's full glory which might help to get it recognised at the bigger companies.
The second series of techdemo's on the other hand would more accentute specific Ogre capabilities, and be more targeted at developers, something i think of might be great is to add integrated help system for that feature into the gui, as some kind of live api and usage tutorial.
