[color=39b54a]Update:[/color] So, I've decided to go with the Central Highlands as was suggested to me. Thus we're going to have the setting where there is a strong ARVN and allied presence. Also, due to the fact most people here have requested to be on the forces of the capitalist powers, I'm going to substitute NPC's and characters on the communist side to balance this out. I will also be introducing a Chinese officer 'antagonist' to be the coordinator of the NVA forces. This way, we can have a character trying to oppose the others behind the enemy lines and directing the enemy forces until we get more people willing to play on the side of the communists. 

If anyone has any more suggestions, please inform me so I can try to formulate a proper starter. This is a major series of historical events, so I need all the help I can get.
