Does anyone think that perhaps 2 disks sort of break the pacing? it sort of did for me with ME2.
Only if you had to switch between disks during gameplay. Now, I'm not sure if console versions would work like this, but when CDs were the standard for PC gaming, it wasn't uncommon for games to be released on more than one disc, and usually, you only needed to switch between disks when installing them, after that, you only needed to insert disk one to play the game, so I don't think it would be As long as you don't need to switch disks during gameplay, if it was something like games on older consoles that were too big to fit on one disk where you would need to swap disks after reaching a certain point in the game or when going to certain locations, I could see that being annoying.
Overall, I'd say that it depends on how big the game is. I wouldn't want them to cut some content from the game simply to keep the number of disks it needs down, but if the game can fit on only one disk, there's no need to needlessly bloat it so it can fit on two, obviously. So basically, Bethesda should use as many disks as they need to make the game they want to make. I mean, back in the day of CDs, I'm pretty sure I'd played games which used five disks before, but since I only needed to use them all during installation, it didn't bother me, the only problem was that the more disks you had, the more disks you could lose, and if you were missing even one disk, you wouldn't be able to install the game. I could live with going back to those games except with DVDs if it meant better games. Although it might cause a problem with the game taking up too much space on the harddrive, I don't mind using more than one disk when installing the game, but I'd rather not have to delete all my other games just to make space for it, if I have a choice.
Besides, digital distribution would be a much better idea (eg. Steam) unless you don't have broadband or like to have the game case next to you.
If the game is digital distribution only, then I'm not buying it, I don't care if it's the Elder Scrolls, I'm not going to get a game through digital distribution.
