Nearly everything about that preview is better than the actual game that was released. I saw no texture popping, and the sound and effects were way better than what they ended up giving us. How can you be thankful for a simply worse product? And it wasn't a matter of "brightening it up and adding color" the graphics we have now are just inferior in every way.
I disagree. Unless you're on XBox, or don't have an actually high-end PC. Or have a PC that has one of the graphics cards the game doesn't work properly with.
I've seen it running on a really good PC, and it looks and plays amazingly well. No pop-in that I saw
It's not as pretty on PS3 or XBox, and XBox does get pop-in more visibly than PS3 (I've barely noticed it on PS3 even when I tried to find some). But it's still a good-looking game, and the animations and gameplay matter more than straight graphics anyway.
