I know that SM:Oddysey will probably get GOTY, but I've played all of Persona 5 and I can say it desreves GOTY a little more.
SMO will NOT win. Just saying that because a stuffty game like PUBG is on there, and it has a massive loving audience, it will probably win. I think the switch sales numbers are around 8.5 million right now and compared to the toxicity that is the 17 million players on PUBG, I think its an obvious winner. Which is sad and makes me want to kill myself, but oh well.
