Why are PS3 games so big!?

UC3 I think is 45gb, because the 3D version of the cutscenes are just vids stored in uncompressed 720p quality in the Bluray. The same goes with KZ3.    The PS3 is powerful, but to render that kind of graphics TWICE would make it explode XD.

I don't think there are 2D and 3D versions of videos on UC3.

Gears of War 3 for example has 3D. But I can't imagine they're storing 2D and 3D videos on a single DVD.

If that is the case, then I dont know why UC3 takes so much data.   I guess that is also the case with KZ3?
