Damned ! That's could become a new social experiment, by this I mean it could be the chance to try something different than the old "alpha male" (or female for matriarcal society type like bees) style, with one or more "leader(s)" who take final decision or just lead and all other following, instead having something like:
- people who want to be involve for a while or a short time, whatever let others know, they do the tasks, report and give their work (a single sprite, texture, sound or class or a full component like a rendering engine)
- all important choices are submitted to a vote, the currently involved people choose by majority and so it goes.
The pros here is there is no need for a few people maintain a living "core" for the project to live (this may need a dummy/"corporate" account which can be shared fr managing project), people would be free to get involved has much as they want until they get bored for example.
To add something to what I wrote earlier also, having many people adding their own brick to the great wall, one at a time, allow these people to contribute how they want and how much they want, so people who don't have so much time can still achieve something they can't do on their own alone.
For the game itself, I think of a city building/management like Millionaire City or Rising Cities, there are not so much game like these and it is rich and wide enough to allow various idea and design. For example, it could include an optional multiplayer component, which could also use social media stuff (FB account for keeping data, sharing stuff between "friends", etc), it could also be designed as Gnu Chess and its rendering program.
I mean, GnuChess is just a chess engine, and there is many visuals which can use it to get classic 2D top view or 3D view (openGL of Win DX or whatever), there could be the game engine, displayless itself (can be use on a server), then many visual clients (top view like Millionaire City, 3D isometric like Rising Cities, full 3D like in Sim City games)
The base game would offer a single player on local computer play, "plug-ins" can be use to play online, use 3D display on a powerful enough computer, and simple 2D top view for keep playing on a phone with the same account, same data, same things currently achieved.
