For one thing, since when does a game with a review score aggregate in the 80s and positive but not ecstatic reviews on release blow past the rest of the field to be THE GoTY award winner?
Dragon Age winning GOTY in 2014 tells you a whole lot more about 2014 than it does about Dragon Age.
AAA releases were just weak in 2014, full stop. Inquisition was the only established AAA franchise in the running which didn't completely fall flat on its face by oozing bugs and compatibility issues. Inquisition coming out in the same year as a GTAV or The Last of Us - no chance whatsoever. Not even in the running.
Couple problems here. Bayonetta 2 blew it out of the water. So did Tropical Freeze. As did Guilty Gear Xrd. As did Divinity. Most of these were polished, tightly designed, challenging games. Even the sloppiness of Dark Souls 2 doesn't reach the level of half-assing that Bioware engaged in, and its core mechanics were vastly superior. There were plenty of superior products. You have the people handing out the awards admitting that there is a ton of dross in the game, but they don't care.
Second problem is the idea that only established AAA franchises in certain genres, that have a console release qualify. This also tells me about the games media. It it's a PC exclusive and it doesn't have the words Half or Life in the title, it won't receive serious consideration.
To understand the situation, there were hardly any good games in any genre, so choosing a GOTY award in 2014 was pretty much like finding the most liked piece of shit among an entire pile of shit.
It wasn't the most liked, and that's my point. Well, it wasn't the most liked until suddenly it's a GoTY contender. But so far it's not among the biggest sellers and the critical reception at launch was good but not ecstatic. What's the user score and sales compared to Mario Kart 8 (not saying that game should be a contender, but it got a bigger response from the masses)?
So if we know the biases (pro AAA console/pro "narrative" genres/anti-Japan/anti-PC exclusive), and we know it didn't achieve mass popularity, and we know that there is rampant conflict of interest in game news industry, and we know it got good but not top scores, and we know there were better put together games, then we know it's not about a weak year, which leaves ulterior motives/political shenanigans or superficial values (big = good).
I mean, this is all just a mental exercise since I know that you know this shit is a farce. We're already getting the usual post-release week backtracking about how maybe the game was kind of shitty, but no it's still really good.
