The Big deal I suppose stems from Microsoft saying that DVD is all that's needed for gaming this generation and saying that Blu-ray is over kill and only used for promoting movies, Sony on the other hand says that using DVD is short sited and that Blu-ray is the way to go because it's future proof3e.
At the beginning Microsoft was justified, but now it's Sony who has become justified with quite a few 360 games needing to come on more than 1 DVD, not all but a few.
If none of the above was said, then the issue wouldn't be as big, but it's not like it's that big as is now.
The simple fact is that having 1 disc is just convenient.
The following are also other things to consider I suppose:-
-Developers can fuck up a game by not making it work smoothly with multiple DVD, which may result in games where you have to keep swapping backwards and forwards to access different sections of the game word and such, while this issue is clearly none existent on Blu-ray.
-Having multiple DVD also runs the risk of having one of the discs lost or badly damaged, in which case the game can become unplayable depending on which disc is lost or damaged, this of course can happen to BD, and both can be negated but the risk is greater when there is more the 1 disc.
-There is Disc technology that can negate the use of multiple DVDs, and that's Blu-ray, it's the format made for HD content in general, so if the 360 had one then their would be no multiple disc issue, however that's not the case.
Now normally games fit on DVD especially when the 360 is the lead platform, but if a developer wishes to create a game with FMV, then they have to think twice about it and not put it on or create a game on multiple DVD's, which in it's self creates more work, BD allows FMV while avoiding the extra work involved with making things work on multiple discs. Thus far nearly all 360 games which have multiple discs are RPGs.
I know most will cite the fact that you can forgo FMV and just do things ingame, and while thats ok if the graphics engine is up to it, but nothing beats having epic things happen with CG which are simply not doable ingame or simple don't achieve the same look.
