Don't care yet don't understand why people always complain about haven to get off their asses and switch a disc either-__-
Its stupid to complain about this, we live in a world were we may have to switch a few discs, big woop, PC users have to deal with that all the time if they have to install a game via disc if it is bigger than average..
I understand that sometimes people could say it "takes away from the game" having to switch discs at a certain point, but if you say it like that than that means having to pause the game does it as well or really anything does, like opening a door that you have brings up a loading screen.
Well, hopefully the new engine will make it so you don't even have a loading screen when opening a door-you open it and there it is, the inside of the building. Even if that's not the case, you kind of expect loading screens to some extent and they're fairly common-they're kinda annoying and they do "take you out of the game" a little but you sort of phase them out in your mind to some extent. That's easy, because all you have to do is sit there and wait for it to load-you can let your mind wander for it bit until the game continues.
A pause screen is an even worse example, you have full control over when you pause the game, it's a voluntary action, you're pausing the game because you want to pause the game-it doesn't take anything away from the experience, and if you're really hard care and never want to pause the game because it "breaks immersion", you don't even have to do that-I'm honestly not sure how you'd get by not using the inventory screen either which kinda breaks immersion as well but whatever. lol
The thing is having to physically go and switch out the disc REALLY takes you out of the game-you have to physically get up out of your seat, go to the game console, press the eject button (unless it's automatic), take out the disc, get out the next disc, put it in, close the tray, walk back to your seat, sit down and wait for the disc new disc to finish loading. True, that's easier done than said but it requires you to physically do something in the "real world" to continue playing the game. It's not entirely unreasonable it's just a far stretch away from the examples you've given.
That said, in an open-world game which would probably need to be divided into "regions" contained on each disc you'd have to repeat this process over and over again every time you "cross the border". It could also cause some serious issues with the design of the game. Basically, the game designers wouldn't want the player to be annoyed at having to swap discs every time they cross between the "regions" contained on each disc, so they compartmentalize many of the quests to just take place in one of the regions or the other-which might be just fine for the two-disc XBox 360 version where having to constantly swap discs would be a problem, but for the PS3 and PC you'd feel a sense of "Why are all the quests given to me in East Skyrim only taking me to places in East Skyrim? Even quests given to me in places that are near central Skyrim don't seem to go anywhere beyond a line straight down the center!"
They can't make an Elder Scrolls game like Final Fantasy VII where there's a linear plot line and the thing that's actually taking up most of the space on the disc are the epic cut scenes. They can't make it something where you get to a certain part in the game and it says "Please Insert Disc 2" and you just continue from there.
To make a long story short (too late) I find it highly unlikely that even if they do put the game on more than one disc they won't make us swap discs for anything more than the installation process.
