neumi5694: Well, they are not allowed to prevent it. So they could not deny your request to support to transfer the ownership of a licences from one account to another. And that's why we are not really owners of these licences.
But if we
were: Implementing a market like they already have for other digital items would be the most cost efficient solution instead of answering thousand of support tickets.
The second hand market is a pain in the ass for all producers. Digital media never showed decay (no matter if online or tangible), so producers tried to introduce artificial decay.
On consoles games are shipped with codes for DLCs. One buying the game second hand won't get that DLC.
The argument you bring up about the millions of users with the huge libraries only is a matter of had BECAUSE second hand was prevented so far.
The laws exist for quite some years by now, so I would not call this "suddenly". I would say: "Guys, you saw this coming for years. You couldn't bother to prepare for it?"
I don't ponder much about if it would make sense or not, I am quite sure that for Valve it would be a disaster. Their business model would go up in flames. But it
does violate laws to prevent people from selling what they own, and something
will change.
If a second hand digital games sale would be a reality, it would mean that the gaming industry would collapse. as second hand would be cheaper, and there is no deteroation of the games (and the market is global, not local as with physical second hand sales), less people will buy games on release rather waiting for the second hand sales. so you will get a lot less day one sales. the long tail (sales after inital release) will disapear completely. since developerss do not see a dime from sales of a second hand market, this means that developers will make
a lot less monies and most likely will not survive = no more games being developed, developers just can't make a living out of it.
it will also mean implementation of much stricter DRM applied across the board. to regulate a second hand market, you need to comntrol the ownership to prevent scam (what would stop me from buying a DRM free game, installing it on my PC, selling the game, but don't uninstall it). the transfer of ownership in a digital market is not easy, and must have some DRM schemes to be able to do so realistically.
Basically, the only way forward for game developers in such a climate would be game-as-service, as then there is no transfer of onwership, there is nothing to resell, but the developers still have an income. This off course means killing off the entire indie scene, and only the large companies would be able to survive (as games-as-service need a much larger infrastructure). the games being developed would be the games that lends itself to such a model. I do not see any other posibility
