Game of the Year: Final Fantasy VII Rebirth
What can I say? It's the next epic installment in the FF7R series. It's got a little bit of open world busy-work, but overall it's a lot of fun, the characters are great, the adaptation is fantastic, it's everything I could have wanted.
Runner-Up: Astro Bot
Asobi did it again, with a full-sized 3D platformer good enough to challenge Mario. This game is such a delight, I'm sure I had a stupid grin on my face like 90% of the time I was playing it. Everything about it, from the way movement feels, to the visual style, to the love of Playstation's history, it's just such a delight.
Honorable Mention: Helldivers II
Like Sea of Stars last year, this game was totally not on my radar, and I don't generally go into multiplayer games, but this one is fun enough that it actually pulled me away from Persona 3 Reload, and I spent basically the entire month of February playing it. The only thing that broke its spell was the release of Rebirth.
