Most developers will likely agree that leaks are a bad thing, but Dying Light: The Beast could be a rare exception.
When developer Techland was handed a large bunch of lemons after reams of information about its upcoming Dying Light 2 DLC was leaked, it decided to get out its juicer (if you still follow this awkward metaphor) and make a big flask of lemonade with it.
Rather than accepting that its DLC was no longer a big surprise, Techland decided to double down and expand its scope even further, to the extent that it eventually justified a standalone release.
