Also, if I would be a game writer, wouldn't present wars be against insurgents and rebels, ambushing and suicide bombing the technologically advanced soldiers (I'd rather not say Americans, due to the fact that present "realistic" FPS protagonists always includes Americans).
I would love a Third-person war game in which you're on the rebels' side of the war fighting against technologically advanced enemies,owning them via ambushes, suicidal-bomber teammates, and dirty tricks. You would be destroying their radar and radio system by hijacking one of their vehicles, commanding your rebels to keep the guards busy while planting mines and traps as well as RPGing all of their sattelite and radio machineries to impair their communication.
I'd rather want a war in which there's other objectives than just running around, taking cover, and gunning everything down.
