I just finished a game of the Korea tutorial, it was interesting. It was quite a struggle for the first 10 or so turns before suffixient reinforcements arrived. On turn 17, I started running POvPO, and the American PO played some interesting plays, but went too far North and awoke the Chinese dragon.
I think that the new supply rules and displaying the supply numbers make a difference in how I play, at least. It makes it very obvious what effects the railroads and roads have on supply.
I did see some strange behavior by the engine. I need to talk it over with the team to find out if they are bugs or features, and whether they're new.
Back to fixing some of the graphcs anomalies I introduced before another big push.
