Implementation and gameplay are fantastic, AI is good although I wish there were a couple harder settings.
There is a bug in the Advanced map such that if you switch to Standard, and then back to Advanced it will ask you to purchase again - it wont actually charge you, but will seem like its going to.
Another bug is when you select Rematch, the game hangs until you exit and re-enter.
Otherwise, I love it!
