I thought he said Mario 3D World was better than Brothers. I also thought he said that about a Zelda game but I don't remember which one. And of course there is DotA. So I voted for fourth but maybe some stuff he rushed to finish before the GotY discussions got to him and dropped it to five or six.
If looking at the year when he got into SC2 that was also the year it was number two on his list and the number one went to Red Dead Redemption. I don't see any other game this year that had the same effect on Brad though that was the same as Red Dead Redemption and Dota 2 was the only thing that really maintained his interest for the entirety of the year and when asked if Brothers was better than Dota, he declined to give any definitive answer. I'm guessing Dota 2 takes his top spot and Brothers takes either third or second.
