It doesn't matter how much the game cost to make to me. As a consumer I care about the perceived value of the product, something which this game doesn't provide whatsoever at $50.
Buying something is not the same as making something.
Like the previous poster said, you have no idea what it cost to develop the game, to get the carts pressed, or to distribute it.
You are just making stuff up.
Everyone's different though, maybe you think it's good value for $50. You don't have to agree that it's a ripoff at $50 but I don't have to agree it's good value either.
