BreOl72: Sure. But not for every
possibly sold game.
That's the crux here: the devs/pubs don't sell as many games as they could, were it not for
illegally kept "security copies".
Because every
illegally kept "security copy" enables an 'owner' of an original game to sell that original game to another interested person, who might otherwise purchase said game from the dev/pub, who (
even if sold with a As far as I know, there is no such thing as an "illegaly kept" copy in germany.
If you currently are in possesion (not even ownership!) of media of any type, you are allowed to make a personal copy of it, unless you need to circumvent any form of copy protection to do so. And if you are allowed to make a copy - I do not know of any ruling or law that says you have to delete any legally made copies.
This means it's even legal in germany to copy a borrowed product. Again, only if you don't need to circumvent any copy protection, may it as easy to be, as it sometimes is/was. Since it's sometimes really easy, it might be hard to really make a legal copy of something.
On the other hand, it's not a legal copy, if you get the hands on someone else's copy. So downloading a backup that is not your's, is actually not allowed, even if you currently hold a legit product.
But to add to the confusion: you can let someone else make your copy. Though both of you need to have legal access to the same source material (e. g. the other one uses your physical media, or public streamed video signal etc.; for the last point, there is even a curt ruling somewhere to be found, from times where online tv recorder where more common).
But in my humble opinion:
I also think it should be 100% legit to want to use and keep and backup something you lawfullly, legally and officially bought for. No matter the laws and rulings. And any company thinking otherwise - or even thinking of taking legal methods, should reconsider.
We can also start not to buy and consume media. And it should be our right to decide on how we want to enjoy that content. Be it on a different ebook-reader, without a CD check or from a bootable usb stick, with or without a launcer and whatnot.
I might consider enforcement of multiple purchases per household to be fair, even if I dislike the idea. But after all you want to play together a product, so it's fair and square to demand multiple pruchases.
