One of my (many) game ideas was a first person shooter ala Call of Duty, but in Vietnam. And make it ACCURATE. Obviously, never allowing you to commit war crimes (it was all a war crime), but instead have some storylines focus on stopping rogue marines. Dense jungle maps. Patrols. Base defense. Helos. Napalm. Some drug use. Fuck, man, and make it serious as shit. No GTA levity. Dark. Graphic. Controversial. Like the war itself. And, lastly, create the greatest soundtrack of any game. Ever.
