Just out of curiosity... and as an ignoramus, I'm probably talking out my [censored] here... but is it remotely possible, given the DLC problems with Skyrim are apparently memory-usage related, that Skyrim+DLC could be made to run using the cloud-storage infrastructure in place via the PSN. I imagine, these days, remote memory via Broadband is probably sufficiently fast to provide acceptable gaming, indeed there are a variety of companies proposing consoles whose working memory would be entirely remote. Where better to keep all those notorious discarded iron swords, embalming tools, cabbages and what-not than a server?
Obviously this would mean you couldn't play any expansions without a broadband connection, but you need one to buy them anyway (possible GOTY's notwithstanding); and I guess you would need PSN+, but that would be only as extortionate as what Microsoft requires for full use of many games anyway... ideally, free PSN+ membership with DLC, or vice-versa free DLC with PSN+ would also be a nice bit of restitution for the fans.
Like I said, I'm shaky on the technical issues, but does the working memory required by the game have to be on RAM? I'm given to understand the game already shuffles data between RAM and HD to play, why not between server, RAM and HD.
Asides from the technical issues that this in almost certainty won't work in the way you describe it, it is a nice idea, but now you're requiring people to pay a monthly fee solely for being able to play DLC. I like some games with a subscription base play, but that would be just so far out there that no one would buy into it. I don't pay for PS+ because I wouldn't get my money's worth out of it for what it provides. It's a great service, but it's not for everybody. I used to have it, but I have more than enough storage for everything I have on my 320gb drive, that cloud storage makes no sense. If this were possible, what would happen to a person's version of Skyrim with the DLC when they stop paying their PS+ subscription? They probably wouldn't be able to play their game since once you stop subscribing, you lose all benefits you once had. All games you bought will no longer play even if the software is there, all free mag videos no longer play, and all DLC becomes deactivated. In a game like Skyrim, where the DLC becomes intertwined with the main game, you can't simply turn it off. It's almost like a patch. Once you download it, it's part of it. I guess you would have to uninstall the game and reinstall the vanilla version. But then all your savefiles that you used after the DLC was implemented would no longer work.
A far cheaper alternative to what have some have suggested (just buy an xbox or pc and another copy of skyrim), but to have to pay on top of what everybody else pays is ridiculous. Remember for THIS game, and you can only compare to this game because outside of it is a different situation, you don't need to pay for XBL Gold to download DLC or receive patch updates, all you need is XBL Silver which is free with an Xbox and internet connection. So asking PS3 users to do something not required by the other two platforms and PAY for it, just elevates the standard of unequal treatment and services rendered for the same amount of money paid.
Either way, this will not end well for Bethesda. The next Fallout could be programmed specifically for the PS3. They could launch a massive ad campaign complete with video evidence telling people this and I don't think anyone would believe them. The damage to their reputation is just too great a mountain to climb right now. Honestly, I see Bethesda abandoning their PS3 division and going 360/PC exclusively. I would be very surprised if they are even trying to program (port) the next Fallout to PS3.
I think they will still try because they were able to fool a lot of people this time around with Skyrim, but like you said nobody will be fooled the next time even if they are really telling the truth. Their sales will go down big time in the PS3 market, and they'll drop it on the title
after the next FO title.
