Being game of the year is more than about being technically the best or the most popular.
Like Oscar wins it can also be about how the medium has capture the moment or was a commentary on the times.
In this regard there is actually no other game that comes close to New Horizons this year.
There are better technical games, there are more dramatic / cinematic games, better online games....but no other game really symbolises 2020, stirred up as much positivity, helped so many people, became a ray of light in an otherwise dark year.
I mean seriously doom or last of us as the game of the year in 2020 feels well almost morbid.
Animal crossing game of the year 2020 feels right.....it was the sun shinning through the clouds, it created a movement in people, so many got behind it and, it even led to brands, celebrities and a future us president getting in on it.
