@CptWinters - The ability to sell a tower and restrategize is in ALL things people do daily. For example, in the winter, if one road seems to be really busy when trying to get to work, the next day instead of going the same way, you try a different route. You have a right to change your strategy and that's what you should be allowed to do. Same is true for most of these games. You can't restart real life, you shouldn't have to restart a game. It should cost something to change your strategy, but it should still be possible to do so.
