I'm thinking about making my shooter, about war in Iraq. What do you think about that guys?

Some more info:

1 - Player will be able to run, will have stamina but his speed and stamina reducing wouldn't change according weapons.
2 - Player will be able to prone.
3 - Player will be able to chose two different classes:
* Marines
* Rebels
4 - Each of class will have own weapon and weapon classes like assault, sniper etc.
5 - Player will be able to have only 2 primary (has only one at the start, second can be picked up) and one secondary weapons at the same time, plus 2 type of grenades (depends on the players class).
6 - There will be no player HUD and no crosshair.
7 - Main aim is realism.

Please tell me if you have some ideas and if you don't like some ideas from above.
