That’s what every game company has said about every game for decades though! A game disc which installs and plays the game was legally still some nebulous “this provides a licence to play the game which can be revoked at any time”, it’s only now that the companies actually have the power to revoke them at any time.
Look up “primehack”, it’s a modded version of Dolphin emulator which is specifically for playing the Metroid Prime trilogy. Modernised controls and lots of little QoL improvements, it’s my first experience of Metroid and I loved it!
Obviously this is all just to get you to subscribe to Prime though, so don’t do it unless you can get a free trial or if you were going to do so anyway!
Note that Dark Souls games are absolute Marmite. I’m aware that some people praise them as the greatest games ever made, but I had a terrible experience playing DS1 and have no desire to touch another one!
My point is that they are representative of how gaming used to be. Good on Germany for treating addiction-based money-extractors as what they are though!
