Incorrect. The game code belongs to whoever holds the IP rights. Games don't get released for a reason and it's not your right to declare that anything unreleased is suddenly in the public domain just because it's not likely to be sold at some point in the future. As we have seen over the years, unreleased games can see second life as download titles or other commercial ventures. You don't get to essentially steal someone else's intellectual property and hard work just because you like video games.
