A new take on In-App Purchase in a freemium game: this game lets you purchase unlimited money. No more nickel and dime-ing customers who enjoy your game. In addition, any other things you buy before buying the unlimited pack reduce the price by that much. Essentially, they are capping what the user can spend on their game. Seems like a fair approach, but it’s still a little sad that freemium is pretty much the only way for a game to succeed.
