HD DVD vs Blue ray for games
polycounter lvl 18
I was thinking about this the other night why would developers need so much storage space? At what point is it too much space?
A DVD can hold 5 GB - 15 GB.
A HD DVD can hold 15 GB 60 GB.
A Blue Ray disk can hold 25 GB - 100 GB.
All the current systems dont have jack shit for texture memory so textures still have to be small. Small textures dont take up that much memory, so the extra storage space is useless there. That is unless you want to have more textures, but that means longer dev time or half ass textures. What about the models, do we need the extra space for the game models? Sure we could fill up the disk with millions of models, but again that would increase dev time. We could make more levels or bigger ones to use the space, but that too would mean longer dev time. We could let the programmers fill up the disk but that would be pointless. That only leaves us with audio, how much music and or sound effects could we ever need or want in a game? I dont see us needing 30 GBs of songs for a game, so dont think well be using the space for that.
All and all I think we have hit a point where we dont need any more storage space, not until we get more system memory in the systems. With our current gen of consoles I cant see any game needing more than what can be put on a DVD.
So what about you, do you think we really need more storage space rite now?

Personally I'd be disappointed to play a Next Gen Final Fantasy without HD cinematics.
Btw, slightly OT but hopefully not too far off. I bought an awesome 40" LCD Sony TV recently, and at the same time the Best Buy rep was trying to tell me that Blue Ray was *infinitely* superior in terms of picture quality compared to HD DVD and that in fact HD DVD wasn't true 1080p at all and he even went as far as saying that HD DVD was no better than current up conversion DVD players. Surely not true? More like BB have some evil scheme to shift thousand dollar blue ray players? I would love to be more clued up on this stuff.

But I have found as of late that Best Buy employees are not up to date on the next stage of home entertainment. I had one tell me the Xbox360 only supported 480p and I would be best off to wait for the PS3. I was forced to show him the video setting on the dashboard....and apparently that was a new setting that came with an XBL update.
but again an HD-DVD is true 1080p.
I think game developers should try to put as many assets and as much quality as possible in the space they are given. In fact, many companies could use less assets, and more gameplay. That doesn't require much room. Think Resident Evil 4 for gamecube, and Shadow of the Colossus for PS2.
We shouldn't be fooled into buying more expensive hardware, and getting little in return.
Maybe the next line up of systems, the "next next gen" will have more texture memory and will give us reason to use more disk space. At this time its pointless for none cinematics games. My guess is when that "next next gen" systems comes out they will have hd dvd as the storage medium. The funny part is that at that point having games run at 1080p wont look like ass because the textures will be the rite pixel density so that they can be crisp. Rite now ps3 games running at 1080p look like ps2 games because the textures are so low res compared to the screen res.
Also remember that the compression used in current generation is far superior to the last generation. Most 360 titles use the 720p WMV video format. It takes around 1gb per 30 min of high definition video using this format. Not many games will have more than 30 min high def cutscenes, even RPGs. As far as sound goes, the 360 apparently offers up to 6:1 audio compression for near lossless audio, and up to 14:1 for lossy audio with it's new proprietary audio codec.
A good real life comparison of previous generation to current generation is the new 360 game Blue Dragon and the PS2 game Star Ocean: Till the End of Time. Blue Dragon spans across 3 dual layer DVDs and contains about 40-50 hours of gameplay. It includes tons and tons of HD cutscenes, much of it being fully uncompressed WMV video. The newest Star Ocean, which was released near the end of the PS2's lifecycle, spans across 2 dual layer DVDs and has about 40 hours of gameplay as well. Keep in mind that Star Ocean:TET is a PS2 game, which means all the cinematics, textures, models, and sounds are low resolution.
Sonic good points, my hi-end numbers are using double sided disks. And that info is all from wikipedia.

Ahh, I knew I was forgetting something
I seriously do wonder why game publishers dont decide to use dual-sided disks more. I wonder, since dual-sided disks are less common, if it would cost more for one dual sided than for 2 single sided.
I would also like to add that I can't see the difference between 1080p and 720p at all. I can tell the difference between 1080i and 1080p because of the progressive scan, but as far as the resolution goes, I think unless you sit closer than like 4 feet from your TV you wouldn't notice a difference.
Then I must be playing it slowly since I was at the 40 hour mark by the time I had to change discs.
For movies though, I'm digging HD-DVD more.
Blu-Ray uses Mpeg2 compression, which is pretty funky. HD-DVD uses the H.264 codec, which is far and above better.
I compared both at the store, before picking up the 360's HD-DVD player. If you have a HDTV and a 360, I suggest picking one up.
