What's the one thing they're not making any more of? Answer: Purple ketchup. Oh, the correct answer is "land"? Well, come on, we can't eat land for breakfast every day. Terra God combines tower defense with the creation of (inedible, non-purple) land. Build towers, grow land, kill monsters. It's that simple. If only the purple ketchup recipe was.
