Disagree. 2019 has been a great year for games IMO. My empty wallet is testament to that fact.None
To be honest I really wouldn't know what game to nominate for GOTY... 2019 has been quite poor in "big" game releases.
I'd put NMS Beyond in there, as it's practically a whole new game.
Those are just the ones off the top of my head that have been released this year. There's dozens of indie games that would be worth a mention too.
There's also Star Wars: Fallen Order coming out in a week's time, and FM2020 also.
