Just has to be released this year.
For me.
Scarlet Nexus for me. I played a lot of great games this year. Persona 5 Strikers. Lost Judgment. Monster Hunter Stories II. Bravely Default II. Tales of Arise. Ultra Age. (gave me Nier vibes) Nier Replicant. Poison Control. Hades (Switch) R-Type Final 2. Cruis'n Blast. Xenocider on Dreamcast (yes released in 2021) Asha in Monster World (great remake) SMTIII HD. Ninja Gaiden Remastered Collection. No More Heroes III. Neo The World Ends With You. Cotton Reboot. Metroid Dread. Caligula Effect 2. Raiden IV Mikado Mix (my fave Raiden game) Curved Space (cool twin stick arcade game) and Crysis Trilogy. Shin Megami Tensei V.
This is just stuff released in some way this year I played and loved them all. SMTV almost won it. P5S was a contender and so was No More Heroes III (love that series) A lot of contenders for me. This was one of those years where so much appealed to me. Scarlet Nexus tho. I was taken by surprise. When it was first revealed I thought it looked like a Astral Chain knockoff (my 2019 GOTY). The more I saw of it the more I wanted it. The game did not let me down but exceeded what I expected. I love the Cyberpunk setting. It's an ARPG but the combat feels straight out of a Stylish Action game from Platinum or something. The telekinesis mechanic is very fun. The story is interesting. I love the Persona social link feature. The visual design is great. Music is enjoyable. 2 different stories to enjoy. I LOVED this game enough to watch the anime. I got all the secret clues. Japan embracing a punk setting with Astral Chain and this is still fresh. Been a long time since they tried action games and esp RPGs in this setting. Tales of Arise is a great game but this was bettr IMO and more unique. I really hope it gets a sequel!
Post your GOTY!
