I mention "Rush for Gold: Alaska", because this is the only other time management game I have played on the Mac. Compared to "Rush for Gold: Alaska", I have found this game to be more of a challenge. I like the fact that I can "paint myself into a corner", realizing that I purchased the wrong building at the time and have to restart. It looks like it will take me longer to reach the end, so the game is good value for the money.
