I think it would give a developer a lot to work with for a campaign story as well as multiplayer games.
Possible expansion packs for fighting in Cambodia and Laos on the Ho Chi Minh Trail. As well as * traps, land mines, claymores, and napalm. Potential for riverboat fighting, helicopter gunships, aerial dog fights (jets). The weapons from the era are the basis for our current technology and some are still in use M16, M60, and AK47.
Multiple different forces (NVA, Viet Cong, Chinese, US Forces including Special Forces (Green Beret, SEALs, Rangers), Australians, ROK soldiers (Republic of Korea), South Vietnam Army, Cambodian Army, and Montagnard Warriors(indigenous). camps, abandoned temples, and air combat. Urban (city), villages, jungles, underground tunnels, small forts/outposts, rivers, hills, p.o.w. There is a lot of material and geography to work with. And to my knowledge Call of Duty (I know it isnt your franchise) has never staged a game in Vietnam. So basically 14 years since a complete game.
I believe the last time EA addressed this war was in 2004 with Battlefield: Vietnam and in 2010 with Bad Comany as a expansion pack.
