I understand the purpose of the thread, but it's impossible to think rationally about GOTY given the massive potential of this year's particularly dense fall/holiday release schedule.
I think it'll be pretty hard to top Skyrim. I also think Dark Souls totally fucking will.
Edit: to clarify, Skyrim, Saints Row: The Third, Gears of War 3, Battlefield 3, Batman: Arkham City, Bioshock: Infinite, Deus Ex: HR, Dark Souls, Rage, Resistance 3, Uncharted 3... it's pretty fucking silly how much money I'll be spending on video games this fall/winter. And yes, it's pretty severe sequelitis, but these aren't exactly Madden/CoD-level abuses; these are all games from quality devs who work hard to deliver polished and entertaining products.
