Restricted used game use will be huge negative publicity. When it comes to normal media they will latch on any irrelevant aspect and cry doom and gloom. Both MS and Sony should do their best to avoid it.

As far as 3rd party system of choice, their will be no such thing unless MS goes crazy with casual controls and 3rd partys are forced to make PS4 their brad and butter.

It's mainly a "chicken and egg" case. There wouldn't be developers without base and there wouldn't be base without developers...

It all depends on who's making the demands: the consumer or the developers. If developers pulled the same move as they did with the PlayStation, then there could be a new console leader, even if it's against consumer demands...consumers would be forced to play their game if there's only one platform with everything.

isnt blocking used games for 3rd parties  to make money as well?  every software company is in the same boat.  think rockstar gtav.  what if instead of 10 million only  1 million bought the game and 9 million got it used.  wheres there profit for them?

Doesn't seem likely with all the third parties being so on board with the PS4 already. Including evil ass Activision.

I think the negatives of used game restrictions will outweigh any sales advantage. For those who prefer physical, even if you don't sell games, used game restrictions will be the equivalent of digital because the games will be tied to either your account or worse, your console. The same worry that anti-digital people have of loosing their access when the servers go down still exists, though there is probably a reasonable solution. Either way, I don't think all publishers really care or consider used games as big of a threat to their profits. Piracy poses a larger threat. Regardless the digital renaissance will negate any reason to push for anti used game measures. Increase digital sales will make used game sales loss completely irrelevant.

Though it's an interesting idea, I can't see it playing out like that at all. Even if the nextbox does block used games and even if this does increase the sales of the games, they still aren't going to throw away all the money they would make from the PS4 release.

if blocking used games is true, it wouldnt factor into my decision at all. Because i dont ever buy used games, i am a person who values taking great care of what i buy and i know all to well how most of the gaming population doesnt share that attitude.

I can't believe this might actually happen; blocking used games.

It's more about the consumer than the developer imo, the developers may well like the no used games stance...but the consumers just won't buy the console and therefore the games -> There's only so far the developer/publisher can push it, the overall power is still in the consumer's hands....

Well until the day comes when all consoles stop 2nd hand games being played that is.

blocking used games will scare consumers, which brings reluctance in making that move.

unless retailers come to an agreement with publishers so publishers can get a piece of the pie.
