Never much liked field runners, but could not say why. Maybe because I never played it until about 12-18 months ago when it came to Android. It seemed overly hard when on easy, and the best I could figure out, you have to sell and repurchase towers at various stages in order to survive and I don't enjoy that style of game play. It is one thing to replace poorly planned towers, yet entirely different when you need to. (Normally when I have to sell, I quit and start over instead)
