This will never happen.
15 or so years ago people were saying the same thing about decentralized social media. Yet here we are.
The problem with decentralized stuff is that anyone can put anything, so piracy will be omnipresent there
This isn’t unique to decentralized platforms. Piracy is omnipresent. Yet people still buy stuff. But to address your question more concretely, imagine the store system is designed to be federated. Any instance owner can decide to what degree they would enforce anti-piracy measures. DMCA law requires a good faith effort on the part of a site owner to stop piracy, so any instance owner who wants to run a legitimate shop must properly vet game submissions to make sure they aren’t infringing copyright, and aren’t plagiarizing. They would also have to defederate from all pirate instances, but they would not be responsible for instances that have nothing to do with their own. People who choose to use the instances for piracy would be off on the margins of the internet, just like they are now.
why would you pay for a game when the seller next store is giving it away for free (or much cheaper)
Good question, since you already have that option for virtually all games, why do you pay for them? My reasons are because I generally do want to support the creators I like, as well as because a lot of pirated content is questionable in quality (ie., potential malware). Why do people pay for Red Hat Enterprise Linux when they can get the same OS for free, even legally? Continuing support in that case. Point is, people buy because they believe the value of buying is greater than what’s available for free, whatever reasons those might be.
and how would you distinguish between “EA” selling the Sims 1 there and “TheRealEA” selling the Sims 1 there for the same price.
I dunno dude, how do we do this now? A stupid checkmark? There’s gotta be better ways than a stupid checkmark. PGP signatures would probably be a good start. Maybe incorporate a web of trust implementation? How does Valve do it? I’m not an expert on the subject, here’s a Wikipedia page about the topic.
Also decentralized card information is a bad idea, so you would either need a centralized paying hub, setup your card with every seller, or only be able to use crypto to pay, all of those are bad in their own way.
Yeah, let that be a problem for the person who wants to decentralize payment systems. A more practical solution? Just include the popular payment methods that already exist. Except crypto currencies, that shit can fuck off.
You gave all these explanations for why a decentralized game shop couldn’t work, but all of them are not only not especially hard to solve for such a platform, but are also just common challenges for all of the internet. It’s like the 90s all over again when people insisted that open-source software itself couldn’t work. Yet, again, here we are.
I am looking forward to playing the Remaster. It sounds like they’ve fixed pretty much everything I didn’t like about the original Oblivion - like the awful level up system. Hopefully they rebalanced the “difficulty” in a good way too. Last time I played Oblivion I remember higher difficulties being boring because it mostly meant even the weakest enemies would take a billion hits to kill.
Skyblivion will be fun to play too.
