Is it possible for Sony to take away a game you downloaded onto your hard drive. My friend says you have it for life and it's not impossible.
Yes Sony could block you from using your content if they saw fit, but it would never happen but it is possible, take for example someone was hacked a few weeks ago and the hacker had purchased a game, Sony blocked the system which had purchased the game and thus they will not be able to play it.
when you purchase a digital copy your not buying it out right, your buying a license to play it, yes once it's on your harddrive you can play it when ever you want, but lets say your system reboots, you lose your PSN account details and cannot get back on, them games you purchased are gone with it
so if you buy it digitally, you have the right to play it forever? What if you always keep your PSN details? Can Sony change the game on your harddrive if they wanted?
In a sense, yes you can play it forever, I think, but considering what has happened the last few days and people having trouble with there digital copies, something seems linked to PSN, so in one way you can play forever as long as you have your PSN details, but then on another lets say 10 years down the line and PS4 is just a past memory, whos to say half the games you downloaded will not be playable again, I mean Destiny for example online game, your'll never go back and be able to play due to it's online model, once the PS4 has gone and PS5 is here, Destiny will be obsolete.
but to your question, in theory Sony can block you from playing any game on your system, which has been digitally purchased. same with any digital format, the people who actually own the rights to the game or music or film, can pull the plug on it and block it, if they choose to, thats not to saying they ever will but they can.
