Mark,
The Pacific Game was my original purchase (what, 2-3 years ago?) so I am aware of the early game.
Truthfully, I think I would be more concerned about the US player being bored out of his socks.
My challenge will be to not over-commit to China, and build enough naval planes.
My last play through, Japan was crippled by not having enough replacement air (a problem they had in real life, I think)
