That's probably because it's an actually working and fun game, not some project where people spent more time giving talks or writing blog posts about it than all the people who can be bothered spent on playing it combined, and which is just a stepping stone to yet another half-assed thing nobody needs. Writing it perfectly the first time isn't possible because you don't know what exactly you're making until you made it, and rewriting it into something that behaves exactly the same for the user, but has nicer code, would be pointless masturbation.
