> unique hardware ID This is vastly more difficult than you think. For example, if you try to use the standard method, which is hard drive serial numbers, it's incredibly easy to spoof AND all prebuilt computers from Walmart share the same serials. Non-starter.

I have no idea why you think it's difficult at all. On windows Microsoft provides you directly with functionality to query the device ID, that's good enough but in reality if you pair it with some kind of online login system it's pretty much all you need. https://stackoverflow.com/questions/47603786/where-do-windows-product-id-and-device-id-values-come-from-are-they-useful https://stackoverflow.com/questions/47603786/where-do-window...

  That is trivial to spoof for a malicious user, as are the Android ones. > if you pair it with some kind of online login system Unity does not have that and there is no way in hell that they will be able to force all players of all games made in unity to sign up for one.

All of those Microsoft device ID variants are trivial to spoof or collide. If you're talking about GetSystemIdForPublisher() and friends like 'Product ID', you get the Walmart collision problems. https://github.com/topics/hwid-changer https://github.com/topics/hwid-changer Furthermore, if you rely on an easy-to-spoof hardware ID system, if someone gets ahold of someone else's HWID (see: database breach, phishing), you can trivially mess with the data. Valve/Microsoft/Epic get around this by spending tons of developer time on this problem and using techniques like fingerprinting and behavior analysis.
