For this to be viable game boiler houses have to be reduced in price by a long shot. The way it is now, You can play for a couple hours maybe then when you get to the third land you have to come back and play for 5 minutes a day. It's not really a game, it's a chore. Not fun.
Any time you make people pay to to keep playing with "stamina, energy or action points" you don't have a playable game. You just show your own greed and fail to gain community support.
I see that everyone seems to like Sanityfairies comment but the game is designed to build up your defenses in a way that changes enemy tracking and coming up with your own path over a period of time. Making the game short would screw up the whole theme and idea of the game. It is to be enjoyed the way it is.
