Was just thinking... since games are so advanced now it might just be possible, only problem would be the market which is likely to be small.
The idea is to place you, the protagonist, in the shoes of a war photographer. Graphics and setting would be similar to all those modern sims like Operation Flashpoint, Call of Duty, etc, with you attached to a combat unit to document it's actions. Your weapons, instead of the ubiquitous rifles and shotguns, would be a modern SLR and assortment of lenses. Different keystrokes equip different lenses. The aim would be to capture photos depicting the conflict, sort of like Time magazine or National Geographic style. Points are awarded for having more up-close-with danger shots.
Along the way hazards to look out for would be low light, especially during night missions, and camera shake when grenades or artillery shells land around you. As you run around the warzone, heavy breathing could also affect the view and have it bobbing up and down with every breath. Using a flash unecessarily when adversaries are near would attract attention.
