That's the direction games are headed—it's not going to be a subscription for a whole bunch of titles, it's going to be a subscription for a single studio's titles, with a different subscription needed for each studio.
The ability to enjoy films/games you have in the past is not guaranteed.
Tha ability to gift your films/games to someone else is not on offer here.
Spying on you is pretty much guaranteed
They are in the money making business, not in the make people happy and still able to play great memories with their kids 20y down the road, occupation.
They want to get used to getting paid more overall. It's about the same lately with most products at the grocery store. Big brands know they wouldn't be able to charge more for the same thing, so they charge about the same for less of the same thing. Your 180g 2 bucks chocolate biscuits box is now a 150g. Sometimes they push the envelopes and up the price just a bit. Because they feel they can. And they do.
I highly doubt their tactics will work much longer, people learn and are starting to see, and angered by the squeeze. Brands would have to invest even more effort to find new ways to successfully trickery, diminishing even further value put in the product itself.
Good on GoG. Games are loved when they are fun, AAA aren't all that fun anyway. GoG's great choice for your wallet.
Back to being able to play good old games with kids decades later, imo emulators will support, at least much more likely so that a console to still be found and boot so long later.
