Seriously, I don't know about the look of this game, I feel the trailer has given perhaps too much away?
Agree, agree, agree! The last ND game I purchased was Shadow at the Water's Edge (SAW). I was finally excited about Tomb of the Lost Queen, and looked forward to the trailer, but as you said, I only got about a third of the way through it because I felt it was giving much, MUCH too much away about the nature of the game's puzzles and obstacles. I generally enjoy trailers as they give you a feel for the game, but the TMB trailer felt more like a video walkthrough!
