Or the developer can do it themselves. When the new Dead Space was released, the original was renamed to "Dead Space (2008)". Similarly the Mass Effect titles had years appended to them when the Legendary Edition was released, even though the names were not the same. XIII was renamed to XIII - Classic when the new one was released. Also XIII is an example of why you'd want to buy the original even when the remake is released, because the remake is significantly worse.
