Good strategy, interesting variety & dynamic gameplay. One problem. The designers have decided that you should only be able to have 3 games running at a given time, unless you make any in-app purchase. Fine. Heres the problem: Many people start games, and then never make a move -- given that its a turn-based game, if someone isnt completing their turn, then... nothing is happening. Ive been waiting on other "players" for 2 days, 21 hours, and 12 hours respectively. I initially tried to use their "Give Up" option, just so that I could start a new game... and it put me in a league full of people who rarely ever play. Overall: Great game -- if I could play it.
