A while ago i was thinking of big Korean War Campagin, when you would command US Armored Cav troop. [ Yes, i know how orginal this is
] .
The story i thought was that north korea decided to change it's policy, allowing russian and chineeese companies to exploit its natural riches (coal, metal ores, etc) in exchange for financial help and new and "new" weapons.
For example, russia decided to sell NK most of their T-64s for almost free (in similar fashion how gremany given Poland their Leo 2s.).
The campagin would probably require modified oob - north korea would need new RPGs, new tanks, new atgms... and so on to be a challenge for the player.
Currently that project is suspended. Maybe i will try to restart it someday...
