Excited?

Lately I've been wondering: "Do we get too excited when it comes to new games? or do we have too much expectations from them?"
I mean, just look at Sim City, Far Cry 3, Dead Space 3, Crysis 3, Planetside 2 etc. I feel it was too much hype around it compared to how it actually is. I'm not saying "don't get your hopes up" but when you see all those in game trailers and how it's looking awesomely and everything, I've burned myself so many times on it.
