Outer Wilds. Will probably stick with me for the rest of my life.
Death Stranding also had some moments that I remember fondly.
Slay the Spire still got an immense amount of attention from me, even though I started playing it longer ago than 365 days. I discovered how fun this game can be with a friend / a group. Building the deck together and making decisions really amplifies the emotions :D.
Demon Souls, first souls like I finished, on PS5. Just an incredibly polished experience.
