This^^

I will say that the gameplay was more of the same thing (more fluid maybe), but why fix something that isn't broken.  However I found myself blown away by exactly what you described.  I'm sure ND will be raising the bar on jaw dropping moments and putting Drake through the craziest shit that only he could make it out of alive.

i actually like the demo A LOT. great atmosphere all around just how i like it, it's just not something to show of at E3 to create a lot of hype. but that's what the trailer was for :D

The coolest part of the demo was how things looked while UNDER the water. Most games don't even let you go underwater, and of the few that do, they usually just tack a grayish-blue filter on the screen and call it a day.

Uncharted 1's best tricks were its animations and surface water. Uncharted 2 built on that with snow and set pieces that collapse all around you. Uncharted 3 is bringing to the table sand, underwater graphics, and changing set pieces that involve water. It seems like a pretty typical leap for the series.

At this point, they're not going to tap anymore power out of the system. It's just a matter of enabling their engine to do things with that power that it couldn't do before (ie snow in once scene, torrential flooding in the next). You shouldn't expect much of a leap in polygons or textures past the first few years for any capable developer.

That's right, I remember you  told us you had just bought a PS3... Did you finally get the original Uncharted or not?

This^^ (again!) I thought the demo was amazing, the whole game world was flipped over in real time! I can't wait for this game!

Game of the Show for me, Just Incredible.

I haven't yet, I'll be investing in more games so perhaps I'll rent for some time.
