The alpha being free is a GREAT idea! The first beta release or so should still be free, And then it should slowly climb in price. Like 25 cents, 75 cents, One dollar, Two dollars, Etc. As the months and years go on, Slowly getting you more money, While still giving everyone enough time to really see how it is without spending a whole bunch of money on an unfinished game. I am really thinking about pre-ordering it the more I read and play. Please let us pay only once though!
