Just interested in the thought process in the way the advanced game restricts DPRK reinforcements if the PRC is passive. Is this meant to reflect less materiel support, or military units being diverted to protect against Chinese incursion?
It seems that cutting off those reinforcements would really limit the aggressiveness of the DPRK player starting around turn 3. It also provides serious incentive to the ROK/UN player to not risk provoking the Chinese response.
Basically , yes. Even though the PRC is nominally an ally, the DPRK trusts no one.
