Zelda is a bulldozer, its mere existence guarantee its GOTY status. Even though I think it shares too many similarities with Breath of the Wild, it had a massive success among the critics and the public racking up perfect scores and millions of sales. I really believe BG3 has a chance against Diablo, Final Fantasy and Starfield, but not against a cultural phenomenon like this. Also GOTY isn't there to promote game quality, merely popularity.

BG3 will most likely win OST of the year though, finger crossed.
