Honorable mentions to Battlefield 3, Guitar Hero III, Halo 3:ODST and Left 4 Dead 2, all of which got hundreds of hours of playtime but just didn't make it to the top ten.
As for your list it is kind of hard for me to judge since I have only played two of them (Skyrim and Mass Effect 3). Both games are excellent choices though.
