Fairly good year for me.
RDR2 was OK...didn't love it, but it was descent enough. Liked the first part more, but that's my inner spaghetti western fan talking, though I expected for Rockstar to make more advancements in gameplay for sequel.
I tried to like Monster Hunter: World, and though it seemsed like a good game, I just couldn't get into it, so I quit after day or two.
Kingdom Come: Deliverance was pretty good - non-fantasy medieval RPG, with lot of very solid systems and gameplay. My younger son loves it, I would, of course, would be more pleased if it was a low magic fantasy setting instead of purely historic (something like TV show Britannia).
Two really good CRPGs taht year, Pillars of Eternity II: Deadfire and Pathfinder: Kingmaker.
Homage to 1997's Theme Hospital, hospital management simulation Two Point Hospital.
Lovely indie game game about exploring the world in land boat/vehicle, FAR: Lone Sails
My favourites from that year are:
Frostpunk, a "society survival game where heat means life and every decision comes at a price" - brutal game that really puts you on the spot to make decisions you don't like, but you must in order for your society, which is always on the brink of collapse, to survive.
and on the opposite end MOSS, being fairly lighthearted VR puzzle-action-adventure with beautiful art and exquisitely charming main protagonist, where every screen is like little digital diorama (unfortunately, as with all things VR, screenshots don't do it justice)
Not really seeing clear winner for overall GotY, so, again, abstaining from vote.
