I've been quite a fan of the Battle for Iraq map and had been thinking that this basic concept could be imported to Vietnam. I figure you have The Americans, South Vietnamese, N. Vietnamese and the Vietcong. Throw in the Ho Chi Minh trail for added fun, maybe throw in Cambodia and Laos as territories. US bombardment on N. Vietnamese cities, Vietcong can attack any S Vietnamese city when holding the Ho Chi Minh trail.
sensitive subject, a lot of inaccurate displays, lack of general knowledge of the situation, the fact that there is an indochina map that would have similar gameplay based on previous attempts, some lack of interest, etc.
