Skyrim.
It was good, but sweet Jesus, the soiled-panted fanboys are so OTT. The amount of abuse you endure when you don't soil yourself at the thought of it. "BUT YOU PLAYED IT, HOW CAN YOU NOT LOVE IT". Any attempts at reasoning with said people, and how they exaggerate your feelings.
Me: "I'll give it an 8/10"
Them: "Why do you hate it so much?! Justify your loathing!!!!!!!"
For me, it's as if Kung Fu Panda won ALL the Oscars, people were naming their children "Dragon Warrior", jokes about "I used to be the Chosen one, then I took a turtle to the pressure point", people going "IT IS THE GREATEST THING EVER CREATED". It's not. It's just not.
"It shouldn't have won ALL the Oscars" is met with rage. "How can you not say it deserved ALL THE OSCARS?!"
It's crazy. Skyrim is a big, pretty, empty, world you can hack and slash at things in for hours. It's single player WoW. The AI is terrible (try running across a body of water). The human interactions are atrocious, and they only really exist to hand out quests. The story is average, and all talk of "you make your own story" doesn't work. It's NOT as many claim, a blank canvas. Every interaction with every person in Skyrim BREAKS the immersion and interferes with any attempts to "create your own story" and at the end of the day, you're playing an NPC. At the end of the day, except the people you personally kill (some of whom you can't), everyone remains unimpacted.
Again, it's fun, but GOTY? In a year with Portal 2, ME2, Shogun 2, Brotherhood, Witcher 2, Limbo, Bastion, Catherine, Deus Ex:HR, Dark Souls, Arkham City, LA Noire, SW:TOR.
I'm not saying all those would be GOTY, but Skyrim struggles to get in to the top 5 in that list, and it pushed out much much better games for GOTY despite being deeply flawed. There is no argument you can make for Skyrim that you can't make for playing WoW, by yourself.
Dramatically, unreasonably, mass-hysterical levels of hype. Most overrated game: Skyrim.
