Uncharted 2 is a game I look forward to a hell of a lot, but I wish Naughty Dog wouldn't sacrifice their integrity with this mud slinging, it's just plain pathetic.
Fair enough if they want to say that they're using the PS3's potential and putting it to good use, but they don't need to bluntly come out with statements like "it's not possible on 360", because all that does is show they're not as good at programming as they should be. Any good programmer can use a little thing called compression.
Fallout 3 looks magnificent and the environments are large and open, whereas Uncharted is relatively linear, and I don't see the environments looking much better on Uncharted 2 logically. This just shows Naughty Dog can't code to the level of Bethesda and other devs save their lives.
If it truly does use up the Blu-Ray, and isn't about 10 times larger and less linear than the original Uncharted, then I'm certain they're just using the rest of the disc's capacity for cutscenes.
