Some from various "top" lists:
Hades
Disco Elysium
Red Dead Redemption 1/2
Fortnite, Apex Legends, Overwatch, any modern multiplayer FPS
Dishonored 1/2
Bloodbourne
Alien: Isolation
DOTA 2
League of Legends (I barely have a concept of what a MOBA even is. It seems like a combo of RTS and ARPG PVP)
Far Cry 3
Borderlands 2
Xenoblade Chronicles
God of War 2-5
Bayonetta
Persona 4-5
The Witcher 3
Return of the Obra Dinn
Half Life Alyx
I've played almost all of the cliche 80s and 90s stuff until you get into the advanced nerd lists that start throwing in A Mind Forever Voyaging and King's Quest IV to keep you on your toes.
I'm interested in a few: Hades, Disco Elysium, and Obra Dinn. But man, I have played a lot of action games, a lot of FPS games, a lot of RPGs. It's hard to imagine every single good action game a "must play!". These top games ever lists are always overinfested with action and FPS games. The IGN top list has 15 FPS and 0 2D shooters. OK.
