So, this is the only map I currently own but im pretty sure they don't get any better than this!
Usually expansion add to games, but this one...completely changes it!
You have the China side making everyone bloodthirsty with it's new auction system and expensive building and then Korea with it's TWO markets, making everyone feel fine and dandy until someone swoops in with an unexpected victory. (and it's harder to screw people over because of the two!)
For the money it is definintly worth buying!
