Using the same formula as @thatfrood's Commuty GotY calculations (vote now before there's still time!) I've gone ahead and aggregated all of the staff GotY lists. Basically, a #1 rank is worth 10 points down to a #10 rank which is only worth 1 point.
The Official Lists:
The results are as follows:
1. The Last of Us (45)
2. Gone Home (33)
5. Brothers: A Tale of Two Sons (28)
6. Saints Row IV (20)
7. Super Mario 3D World (17)
8. Assassin's Creed IV: Black Flag (16)
9. Papers, Please (15.5)
10. Rogue Legacy (13)
Compared against Giantbomb's Top Ten
1. The Last of Us 2. The Legend of Zelda: A Link Between Worlds, 3. BioShock Infinite, 4. Gone Home, 5. Brothers: A Tale of Two Sons, 6. Assassin’s Creed IV: Black Flag, 7. Dota 2, 8. Divekick, 9. Papers, Please, 10. Rogue Legacy
(note: These thoughts were formed before listening to the Best Game section of the day 5 podcast) The lack of SRIV from the official list doesn't completely surprise me. While it scored decently, I imagine for most of them it was more of a guilty pleasure type of game in a year where they all needed some guilty pleasures. Most intriguing is the placement of Divekick on the official list considering that it ended up higher than Rogue Legacy despite the fact that Jeff, the only person with Divekick on their personal list, actually has it ranked lower than Rogue Legacy.
And here's the rest - Dota 2 (10) ; Antichamber (9) ; The Stanley Parable (9) ; Rayman Legends (8) ; Gunpoint (6) ; Year Walk (6) ; Divekick (5) ; DmC Devil May Cry (5) ; Beyond: Two Souls (4) ; Grand Theft Auto V (4) ; Dead Rising 3 (3) ; Fire Emblem: Awakening (3) ; Metal Gear Rising: Revengeance (3) ; The Swapper (2) ; F1 2013 (1) ; Tearaway (0.5)
EDIT: Oh yeah, The Last of Us, totally figures.
