Outside of review codes, I didn't beat all that much this year. I dabbled in plenty, and also spend a lot of time trying out games in beta/alphas, but this year marked more the year of "If I'm not enjoying my time with this anymore, don't chase bad time after good" for me.
Games I beat (or are run based):
God of War (PS4)
The Last of Us Remastered
Bloodstained: Ritual of the Night
Control
Toejam & Earl: Back in the Groove
Super Mario Maker 2?
Fire Emblem: Three Houses
Outer Wilds
Risk of Rain 2
Dark Pictures: Man of Medan
Nowhere Prophet
Apex Legends
Final Fantasy IX
Games I played and want to finish:
River City Girls
Sekiro: Shadows Die Twice
Luigi's Mansion 3
The Outer Worlds
Link's Awakening Remake
Untitled Goose Game
Neo Cab
Games I played but won't beat:
Crackdown 3
Void Bastards
Devolver Bootleg
My Friend Pedro
Games I want to play from 2019 but didn't get around to:
Life is Strange 2
Disco Elysium
Katana Zero
Astral Chain
Daemon X Machina
Slay the Spire
Persona Q2 (after I finish Persona 4 Golden)
Dragon Quest XI
Beyond the above, I played a ton of Rocket League throughout the year, and a BUNCH of Smash Bros over the holidays. I've also done some rounds of Apex Legends and while I have fun with friends, It's something I could never bring myself to play solo.
