Ok, here I will post from time to time some game-play ideas that come up in my mind. Everything is PD (ideas are cheap), so if you want to create such a game, no problem (maybe I will even help out)
--------------------------------------------------
First one that came to my mind while looking at some civil unrest tactics used in Egypt, is why not make a "riot" simulator as a kind of RTS, with one side playing the police/military forces and the other side the protesters.
Could be done as a multiplayer game, with one guy controlling top down the police forces like a traditional RTS, and a group of others in a more FPS fashion with squad commands etc to guide the protestors.
Non violent strategies could be implemented, but also some "not soo non"-violent On the police side you have the water cannons and possibly tanks etc.
If done with really good attention to details and the right political ideas behind (heh, that's the cool thing about FOSS: not having to worry about customers), then it could even become a training simulator for protestor tactics, and maps could be shaped after real world locations (I would love to see the mainstream media echo on this kind of game ).
