Would have given 4 stars if the game didn't contain as much adds. I understand the developers need to make a profit, but there's a fine line between funding and annoying. Adds are shown when the player agrees to a reward (which is actually a nice way to incorporate adds) but adds are also shown when the player is navigating the game. So I see about 10 adds each time I play, which is a bit too much. Otherwise, the game is an addictive nice spin on the tycoon genre.
