The title "The Good Life" constantly shows extreme switching between two price points - around twenty and around two Dollar / Euro. Why?
Probably because there are indeed two different games with the exact same title, one about a ship, the other about a town, The town game constantly costs around twenty, the ship game around two Dollar / Euro.
So probably if you want to buy the town game for a cheap price, you instead get the ship game. Admittedly, the seller can show a description and pictures of the town game. However, you definitely get a game with the title "The Good Life", and you do not know whether it's the ship game or the town game. The true meaning of the key is revealed only after activation - and thus a refund seems impossible.
