Wow,there's not much I can say here other than the fact that you'll lose pretty quickly. I think playability goes hand in hand with balance, so I'll explain more there.
Good gravy! Is this one biased tward your foes or what? First is the fact that the units you start out with are one age behand making it a real pain to do any land invasions, so you'll have to rely on sea and land. Ok so now you've gotten a good force together and taken over Taiwan, now what? Well, this is where you get your butt kicked, first you've probably lost a lot of troops in your invasion of taiwan, so rebuild right? Too bad you can't build fast enough to take over the the rest of your foes before they decimate you. Also did I mention how your "Allies" North Korea and Russia do nothing but just stand there? I didn't did I?
It's creative, I'm sure china is going to either merge or take over taiwan at some point, but never would it get as big as this.

Great map, though I don't think the US controls that much of the Pacific.
No offense, but it's hard to read what you're saying.
