5: Sekiro - One of the best modern works of gothic horror in any medium (yes better than Bloodborne and Souls). A tight central narrative tied into a much deeper lore than is apparent at first glance. Also informed by Buddhist morality, which is pretty cool.
4: Ark - You can shoot a rocket launcher at robots from the back of a Giganotosaurus. What's not to love?
3: Spec Ops: The Line - A controversial game, but one of the only shooters in existence to actually critique the bloody imperialist power fantasy that all modern shooter games inherently are. It spat on Call of Duty and gave the finger to every ooh-rah Marine dipshit who thought they were buying another game to fellate themselves with.
2: Disco Elysium - self explanatory
1: Journey - Less a game and more an interactive therapy tool. Helped bring me out of a major depressive spiral way back when. Play it on mescaline and it becomes a spiritual experience. Also a playable deconstruction of The Hero's Journey story framework, which I just enjoyed aesthetically.
5: Trails of cold steel (all of them) - the Legend of Heroes series is one of my favourite jrpg series, and those are the ones from this decade. They are slow paced, but the worldbuilding and background lore are fantastically done , and the gameplay itself is fun
4: Rimworld - dwarf fortress with less of a learning cliff, a ui that doesn't hate you and is iiiiiiiiiin spaaaaaaaaaaaaaaace
3: Digimon Story Cyber Sleuth Complete Edition - Fuck you it's great
2: Factorio - It's factorio
1: Stardew Valley - Harvest Moon but better in literally every way
RimWorld is great :)
