Quote: "but the used car will have worse quality - a used game won't, and if it stops working, you can pay 2$and have it remade basicly."
A used game has less value than a new game. Also disks can get scratched or dirty, they can have some wear and tear, the packaging and booklets can sustain wear and tear as well. Yes, so long as the disk works you're getting the same gaming experience.
But if people wish to use the used car analogy, a second hand car can be in fantastic condition and can be 'like-new' and it would be as though the person bought the car new, except the manufacturer isn't benefitting from any profit and the person buying the car is paying less because it has mileage. You could argue a person is getting the same driving experience as somebody who bought the car new.
Another way of looking at it, look at the growth of the video game industry, there's a lot of money to be made from video games and it's why video game companies are able to put so much investment in it. People have been able to trade, lend and swap games for decades and heck, people have pirated for decades (though I would argue piracy has hurt the PC games market), even before the internet, which is why it amused me that the Final Fantasy VII PC rerelease had such a crippling DRM, like they were worried people were going to pirate it, when the original release of the game had no protection against piracy, so it was a bit too late.
I don't see how the video game industry is hurt by me buying second hand games, if the game is in a series and I enjoy it, I could end up buying the full priced sequel. Or it may reflect good on the developer and I may buy a game by the same studio (this is why I have so many Bioware titles on my shelf). It was a second hand copy that got my dad into COD and before he got bored of them, he was getting brand new copies, same for my mum and the Lego games. I bought Arkham Asylum second hand and Arkham City full price and will prolly get Arkham Origins for full price as well. If I like the game studio, I might look out for some of their other games, like I have been doing with Square for years and Square Enix have taken a lot of money from me over the years.
Then of course, consider what happens when a game goes out of production. For example Final Fantasy XI and Tales of Vesperia, the 360 versions of each are rare in the UK. I had a hard time finding Tales of Vesperia even second hand. The same for Final Fantasy XI and with FFXI, I paid a subscription for quite some time (heck, I still do), had I not had access to a second hand copy, I would have never played it and it wouldn't have me anywhere near as psyched about Final Fantasy XIV:ARR, I might have ended up getting hooked to a completely different MMO.
So from a personal perspective, I don't understand what they hope to achieve by restricting gamers. The current model for developing and playing games has already been shown to work and works for other media like DVDs, CDs, books and so on. With the current model the video games industry experienced a massive growth. I wouldn't say people trading games is a threat to it, the real threat to the games industry I would say is stagnation.
It would appear Sony realises this. Given the reaction to the XBox One's original rumours and then some of their statements, it's testament to how restriction affects the games and frustrates gamers. Before the PS4's announcements, I was beginning to think I wouldn't be interested in the next wave of consoles. Of course, XBox One has room to make a comeback, but I think for me to be personally interested, it needs to change some things. I am disappointed because I loved my 360 and I am actually still hopeful the Kinect could eventually be cool, it just needs the right people developing for it. However, sad to say, it is the restrictions that are preventing me.
Heck, it was restrictions in PC gaming that could have deterred me from coming back, but I would say Steam is its saviour. Yes, I can no longer trade PC games, but Steam sells them cheaply and you can get good deals on sales - in fact, the Steam sales raid my wallet. If XBox One games were like that, I think it would be more bearable. Though, with Steam digital downloads I permanently own the game, so the advantage is if a disk is scratched, lost or deteriorates, I don't have to buy the game again and not only that, I am legally able to back up my games on steam, in fact, I have a hard drive full of my backed up games. Even if XBox One were able to match that, they still have other problems deterring me from purchase.
