Great idea, mediocore excution.
There is a lot of potential, but the game is reeeeeeaaaaaaaaally laggy on my Macbook Pro running 10.6.8 and its not because the graphics are killer (though they are nice). Trading in this game is kind of a pain when it comes to multiplayer hot seat. There are definitely ways to make this game unbelievable for multiplayer. For example, if it is possible, the ability to project the board on an iPad, laptop, or Apple TV and have the players individual resources, points, development cards, etc. on an iPhone or other (i)OS device. But the multiplayer is really secondary till you get the bugs out for 10.6.8
