I feel like the only reason this alpha exists at all is because they want the whole word of mouth thing going on now instead of later. The amount of free advertising they get by offering an alpha, even at this high of a price, is going to be huge. Based on what I've read from their forum ,they dont really want people having the alpha at all. (minor speculation) They are only doing this because someone thought it a great idea to give people alpha access if they spent 90 dollars on a game that didn't exist.
