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.
The Quest for Glory games don't get the love they deserved, they were awesome games (and waaay better than all the Kings Quest slop). 2nd and 4th definitely the standouts, but I looooved the fantasy African mythology setting in the 3rd one and I wish we saw more of that sort of thing (and it's a shame it was so short and didn't really stick its landing)
The whole series is an incredible package. The changing setting plus how some decisions from the past games are acknowledged and your class affecting quests. If you haven't I would really recommend playing Heroine's quest ( https://store.steampowered.com/app/283880/Heroines_Quest_The_Herald_of_Ragnarok/ ) - it is a free game some guys made as an homage - a quest for glory game with a female lead in a nordic setting.
