The problem is that when I pull out my old PSOne I can put the disk in and sit down and play a game without any issues where as with the newer consoles if you have online activation the life cycle of that game is tired to the activation servers which might be turned off a year after the game came out. Since a lot of people that grew up with the NES, SNES, and similar systems are now having children of their own, they can sit down with their kids and introduce them to a game that they enjoyed as a child. Will the children that grew up with the Xbox One be able to do the same thing? For that matter, a year or two after you played a game would you even still be able to play it if you wanted to?
Nope, and this is the "poison pill" that will keep me from buying one. I routinely play retro games and at some point in the future MS will turn off those authentication servers which means I'd have an entire generation of games being unplayable. I can understand online multiplayer servers being shut down, but most of those games have a single player campaign, not to mention the single player gamer or those with offline multiplayer I'd like to go back to. If they don't change their mind on this single "feature" it's enough for me to skip it entirely, regardless of what games they have on it.
