It got good coverage. Although it might just be my taste but I felt the ads themselves were lacking - they really didn't sell the game well IMHO. The ones I saw were miss-mashes of gameplay footage with little feel for the games overall style.
I think they should have sold it as an Indy type film except you get to do the punching, leaping and shooting.
I did think it has less build on the internet though - when I think how early the hype started for GOW on 360, with articles on the 'Destroyed Beauty' theme etc. I do wonder whether Uncharted could have hit a lot harder with the kind of AAA build behind it. Mind you it would probably have needed some sweet MP to get anywhere near GOW levels of sales no matter what advertising it had.
Still, sales on console base for PS3 are good for a new IP and I think Uncharted will continue to show legs for a while yet.
Try to be reasonable... its easier than you think...
