I think there's something lost on those decrying Expedition 33 for cleaning up at the awards, Award organizations like this, if they are well run, aren't just handing out trophies for the best game. They're handing out trophies for games that are excellent AND fulfill the a message that that organisation is a) reflecting what the audience wants in the industry, and b) is trying to send to the industry on what is expect from it going forward.
KKD2 may be the better game (which I'd agree with to a point), but it isn't as poignant a message that for a game to be excellent, it needs to push the envelope in creativity, art design, original story, dialogue and VA. In other words, it doesn't juxtapose the negative trends the industry has put forward as strongly over past years: lack of creativity, monetisation, repetition etc
I'd even venture to guess that if you asked many of those who voted for Expedition 33 across category would in fact say that KKD2 is the better game. But it's not the one that should win the GOTY award.
In any case, I consider it a banner year when people are arguing so passionately about which game is best out of what nearly everyone would say is a cadre of amazing games.
