I don't see why they would eliminate the disc entirely, it might save them a $ per game, but I reckon it would cost them customers in areas without internet or certainly poor internet. I know that this is a long term strategy, but I certainly don't see a reason for them to eliminate discs entirely this generation. Some larger games are going to be >20GB and lots of people are not going to want to download that much. But I am old fashioned, I buy as many of my steam games as possible as boxed copies then active them on Steam. I get the convenince of digital and have a nice physical collection

I think it is true that they want to push downloads from their store, as obviously they get a greater cut and are certainly anticipation a greater take up of digital downloads. It just makes it easier for developers to keep everything on a level playing field

If it really was all about ensuring that people don't sell their games while still having them installed, then why can't they just have offline mode where you have to have the disc in the console? To me that seems perfectly reasonable.

Because of  the lack of disk you need to connect every 24hrs, and so far cant sell a game to friend so that he can play it too.  You can only sell the game to a retail store.

Those a re the things people are complaining about, and those are because of the lack of disk requirement to play games.

That puts extra work on the disc drive and less convenient.

That's almost certainly a load of nonsense. It's just a data disk. 

The reason why pc games aren't on blu ray is much more simple than that. 

these are just theories not facts and to support the theory further there are various BR royalty program http://www.one-blue.com/royalty-rates/ and sony being one of the founders of BR, it wouldnt be surprising if they got some kind of BR exclusivity for their console, as PS3 was one to the reason Sony wanted to develop BR, and it was because of PS3 that BR won the war against HD DVD.

*again these are just mere speculation! and to me this seem to be the most logical theory behind MS DRM

the "games on blu-ray exclusivity for sony" was a rumour some weeks ago, you don't need a lawyer for that.

topware brang some game collections on blu-ray to pc but nobody bought them. 

blu-ray discs are more expensive, blu-ray drives aren't very widespread for pc and physical game sales are already low on pc with few excpetions.

there is just no reason to release games on blu-ray for pc. some games need multiple dvds because of too less space? that's right but since you install pc games and need only one disc as verification, there is no disc switching and with that, nobody needs blu-ray games on pc.

just to clarify, it was never the case of "games on BR exclusive to Sony" but "console playback exclusivity". As the pc is not a console, it would be fine to have pc BR games, it's just that no publisher would really use them in place of multiple cheap dvds.

I was thinking on why M$ needed that kind of DRM; I know it is obviously due to the fact that all games required to be installed in the console without requiring the disk in order to be played (so in order to prevent the disk to go to endless quantity of users, they need to register the disk to your ID, and go online every 24 hrs, so that you are unable to play the game if you sell it).    BUT why the hell they require every game to be installed in the first place? and why the hell the disk would not be necessary? I think it is because to Bluray licensing.    The disks are just only content providers in this case, so the content is not played directly from the disk in order to be played.   I bet that by doing so M$ is paying less for rights of using Bluray as disk format.   I would not be surprised at all if when playing a Bluray movie, before it actually plays, that it would copy a small part of the movie (200mb) to the HDD, and as the movie plays the content in the hard disk keeps changing.  It would be something like "streaming" the content from the BR to the HDD.

They could have avoided all the BR problems if they made a custom format for their games, just like Nintendo, BUT if that was the case they would not be the media center of your living room, as they are aiming to be.

And, well, considering Sony does not have to worry about any fee of the BR, they dont require every game to be installed, and if you install it in order to enhance the loadings, you would still require the disk (because they can actually read the data from the disk), so the problem is avoided.

So people what do you think about my theory?
