Doom Eternal on Switch, been more than three years since a game I was this hyped for came out.
Also getting Immortals Fenyx Rising.
I don't think any publisher released more than 1 game I bought in 2020, so the winner would go to the one who published the one I liked the most; right now that's Private Division for The Outer Worlds, but its likely about to change to Bethesda for Doom Eternal in a week's time.
