Mother 3 did it before it was cool. In the beginning of the game, money doesn’t exist and you can get whatever you need for free from the general store. Aways into the game, the pig army takes over, introducing money and ‘happy boxes,’ and everyone in town starts working industrial jobs to keep the pork machine running.
Oblivion is cool, but I’m with everyone else that want to see Morrowind remade first. I’ve been personally holding out for the Skywind mod for several years now. I just checked up on it and, yeah, they’re still workin’ on it.
