What game should i get Skyrim, Mw3, Battlefield 3, or Dead island, gears of war or the new assassin creed?

OK i really want Skyrim and i just got up to 60 dollars to reserve it but now i am having second thoughts about it and Mw3 looks like its going to be the game ever one is going to be playing because ever one plays Mw2 and black opsi think if i get Skyrim and after a couple of weeks of playing it i will get bored of it but i have seen demos this game looks really fun. and mw3 look really good new stuff but it looks like an upgrade just to mw2 and battle field looks like its going to be an awesome game and i think it is going to be game ever one is playing to and i don't know if i get mw3 my friends will be playing battle field 3, and dead island i have been waiting like 2 years for, and assassin creed i really want to know what happens to the main character and battle field 3 looks like its going to be a awesome game please help?
