As LRFLEW mentioned, some visual reminders of rules would be helpful, I think a goal beyond score would be nice too. At first I thought that the territory lines got pushed by the dice and this could be a good way to show how the war is progressing and have some end condition like pushing three lanes to your opponent's side.
Also, a small bug: when you sell a 20-sided die from research the game gives you 3 materials back instead of 2.
