OH NOEZ!!! As time passes, games get larger, and that's why we move on to larger storage mediums?!?!?! No way, because M$ decided to stay with DVD9, so games will NEVER be larger than that!
*Sticks fingers in ears* lalalalalalalalala I DON'T WANT TO HEAR THIS!!!
Back to reality:
This is totally possible and reasonable, when you think about it. As console generations progress, games get bigger, plain and simple. GoW2 was WAY bigger than Tekken Tag Tournament. Hell, Gran Turismo 4 (which came in the later years of the PS2's life) is bigger than Oblivion on 360. All you 360 fans who swear that a last generation medium is enough will have to come to grips at some point that it simply IS NOT ENOUGH. PS2 tried to go with those blue disc CDs, but games got to big, so they took advantage of the integrated DVD player, and made games on that medium.
If games don't get bigger as time passes, then why aren't we still using cartridges then?
Those using the compression argument...that only goes so far. As many have said, you also have to DECOMPRESS all those files, and that takes resources that normally help keep gameplay tolerable. A 50GB getting 1/2 compression won't fit DVD9, so that kind of compression is ruled. But then someone will pull out that so encoders can compress up to 100x....well, do you know how much of the CPU that would take to decompress all of that? Just imagine GTA with choppy framerates (a real crapfest, not just those alpha build "choppy framerates" from back in August) jaggies EVERYWHERE, audio lag, etc. and you'll realize that MAXIMUM COMPRESSION!!!!!!! is just not viable. Maybe M$ should have just put HD DVD in the system, so this wouldn't be a problem, or would that have messed up their plan to beat everyone to the market, which in turn resulted in the release a of shoddy product?
