[quote name='BattleChicken'][FONT="]Using space and wasting space are totally different things.
Doing something in an inefficient way in order to fill up a disk does *not* justify the larger format.
If I stuffed my car so full of packing peanuts that I couldn't sit in it, Would that mean I need a bigger car?
I see a glut of prerendered videos in this generation like packing peanuts.. they could script using the in game engine, and it could look amazing (like in Gears of War)... doing it all as prerendered really balloons the space 'need'... but it's not a good way to USE the space.
Look at Resident Evil 4: A lot of the scenes in the game are very cinematic, and could have very well been prerendered... but the knife fights.. and dodging were all scripted, so I wasn't watching, I was still playing.. waiting for the 'A' button to pop up, if i missed the 'A' button, I'd get stabbed or chainsawed -- It was cinematic but also kept the player immersed in the game -- If it was a prerendered cinematic, it would have been less interesting and exciting.
When a developer uses the space to have exceedingly complex AI, and textures, and character models... *then* I can see a use for the space, but for the time being, realistically, the 'need' for Blu ray or HDDVD for games is manufactured.
Someone WILL eventually make a game that truly *uses* the space on a Blu ray disk, but.. to be honest... DVD9s are cheap, and since multiple disks don't add ANYTHING to the price to the consumer, I couldn't care less about changing a disk every 20 hours of gameplay -- but that's my opinion.
edit: I might be wrong about RE4, It's been ages since I've played it, and I don't recall if there's a ton of FMV in it -- Gears is still a really good example of using the in-game engine.

I think you misunderstood me. I never said that blu-ray was needed. I don't think anything that large will be needed for a while, I just say that it is being used. I'm sure every game this gen will be able to be done on DVDs. The problem with that, is that it adds extra and unnecessary effort on the developers part to make a multi-game disc, or to try and budget space so that it does fit on one disc. Extra time and effort that could be going towards making the game quicker or better. For the consumer, it isn't such a big deal, though. I could care less how many discs I have to swap. I didn't mind it in the PS1 days, and I wouldn't mind it now.
[quote name='happy']I would be shocked to find a game with a world big enough to justify constantly switching disks. My concern would be the disk size affective quality of graphics.
For example, if a game were to eventually look like advent children in HD, which presumably should not be that far out of next gen reach, how much actual gameplay could fit on a single dvd. I have no idea what the answer to this question is, I just know a 2 hour movie not in hd takes up a good portion of a dvd. (I also know graphics can be compressed, but that means loss of quality)
I also don't think graphics are everything, which is why I do not want a majority of disk space beings devoted to them[/QUOTE]
Graphics will never really take up an excessive amount of storage space. The things that take up the most space are audio and video. Even games with the greatest graphics could take up little space if audio and video were toned down.
