Let me see if I can catch most of the stuff I've played from the decade too so people can gauge my taste from my top 10. Note: I'm going by NA, not original release dates
Top 10, in no particular order:
Risk of Rain 2 - Still a fantastic roguelite, even after some bumpy patches after Gearbox took over. Can be fun single player but my best memories are with my friends conquering the Eclipse difficulties with the whole cast. Looking forward to DLC3 next month!
Helldivers 2 - Democratically approved TPS that is either the awesomest shit ever or a broken piece of garbage, and I love it.
Street Fighter 6 - Coming from a long-time SF player, the best the franchise has ever been imo. Art design, character balance, system mechanics, and just how fun it is to play. Music's the only step down imo. Melty Blood: TL for example blows it out of the water there.
Hades - Roguelike with a great loop and just as great writing and performances.
Trails to Azure - This one's cheating considering it's def. a 2011 game just super delayed but Azure is awesome and this is my list. As opposed to Sky which is comprised of wonderful character stories, Azure is the glorious build-up and culmination of a political drama. It's a game so good I found myself wondering how it followed such a mediocre predecessor (Zero) that felt like a whole game as a prologue to this one.
Chained Echoes - The RPG inspired by SNES RPGs that actually delivers. Innovative turn-based mechanics, great music and world, decent cast and writing. Biggest criticism is the localization at the start is rocky.
Gravity Circuit - Fast Mega Man X where you punch things, run even faster, and grapple swing even faster. Short, sweet, fantastic.
Record of Lodoss War -Deedlit in Wonder Labyrinth - Short Metroidvania. This one grabs a spot largely on the back of gorgeous sprite work and a balls-to-the-walls soundtrack, although the gameplay's definitely not bad.
Lies of P - What Elden Ring should have been (ER's still
fine, but Lies of P is the true inheritor of the Dark Souls spirit).
Witch on the Holy Night - I'm cheating again. This is a visual novel, and a 100% static one too, but it's so gorgeously drawn, shot, and directed with an impeccable core cast (and seiyuu) that I want to give it a spotlight.

This list is actually pretty short considering how much I game, but I also tend to play the same games a lot and I tend to dip into my backlog a lot too, which, after going through my Steam history, happens to be often.
