there have been some most crappy and old, cod5 should have been vietnam
There's been two Vietnam games on PS2. One was Nam somethingorother, the other one was Conflict : Vietnam.
Shellshock: Nam '67
My problem with a 'Nam game would be the psychological warfare the VC used, and how it isn't nearly as effective to today's gaming generation, who are generally so detached from their game that it doesn't even cross their mind that they have just killed someone. The VC would strap five-year-old children with explosives, and send them off in the direction of Allied troops, saying that the Americans, South Vietnamese, or French would give them food, water, medical care, and/or their families (which were in all likelihood dead already) back, among other things. At this point, a soldier is given a nerve-wrecking decision - put a few slugs in the cranium of the completely innocent child who was told that you were their salvation, or try to help the child, and put the lives of yourself and your fellow troops in mortal danger, and try to help the kid. Guess what happened to the explosives of the soldiers tried to do the second option.
But in gaming, it's much different - you just shoot the kid, otherwise your avatar is "killed" and the dread words "Game Over" appear on your screen and you have to work through the last half-hour or so again. There is no hard decision to make.
Sure, realism isn't equal to fun, and I don't want kids, adults, and vets getting PTSD because of a video game, but it was such an integral part of their tactics, that I can't imagine a singleplayer game without it - aside from botfests like BF:V.
