TESV should come on 2 disks, one install disk that has all the stuff for the game like the textures and models and engine and [censored] and a Play disk that has all the sound and dialogue.
I agree, to an extent. While I do personally prefer Morrowind's dialogue system, I would be more than happy to have an Oblivion esque dialogue system, if it used an extra disc. I believe that there should be two/three discs;
Disc 1: The main game. Nothing more is needed. Includes the meshes, textures, minor audio (footsteps and battle cries), and the actual game world etc.
Disc 2: Voice files. Every single voice, outside random battle cries and greetings, should be included in this disc. If this disc isn't loaded, a Morrowind style dialogue system would appear.
Disc 3: Only needed if Disc 2 is too full. This would include all the extra coding for physics and AI. A very well created realistic world would need a full disc, I'd imagine. This could help a lot.
The game would work solely with disc 1 (thinking about console users that only have a small hard drive. Although they can buy bigger ones, some people can't afford it.), disc 2 and 3 would be completely optional. Disc 1 would really be an advanced version of Morrowind, and disc 2 and 3 would improve upon it.
Unfortunatly, companies seem to have some stupid fear of allowing console users to have multiple discs. They also, even more stupidly, feel the need to cut from the PC game when things are cut from the console version of the game. I really doubt Bethesda will take this route, which, imo, is by far the best option. I just hope they come to thier senses. This is easily done.
