Not a zoomer, but I loved Spider-Man, didn’t play BG3, but I still think BG3 should win. My Spider-Man 2 experience was too buggy for me to consider it for GOTY, the story was great, and if they had delayed the game until next year, I probably would have considered it a contender then.
BG3 was an event though, I’m not really into RPGs but it felt like that game was everywhere like Animal Crossing: New Horizons was in 2020.
