In the current state, it is easily worth 30 dollars. Now, if Craig consistently updated it (which he refuses to do) then it would be worth no less than a good 90 dollars because when he chooses to add updates he is reliable in adding content that improves the game significantly. Because he refuses to update, sure, it is worth 10 dollars, but do not get your hopes up for more updates any time soon. I personally think the endless community needs to give Craig a push, but they clearly don't desire continued updates enough to actually mention it. Regardless, yes it is worth 10 dollars, even more.
