That's not what the article says. This is basically a save game for every-ish moment in the gameplay + a facility to launch the game at the scene you're watching a video of, which is massive amounts of data + progress sync, so if they figured out how to do that at scale, it's legit innovation.
So isn't this like what stadia wanted to do with its integration with YouTube where you could watch someone's letsplay and there'd be a button that could take you to where they were so you can experience it or see if you can do better?
How were they able to patent it if something like this was already described by another company years ago?
To me it sounds more like hitting f8 reload but being able to choose the f5 quicksave from any point in the game, not just the points that you remembered to save or your most recent f5?
