which games are the best in steam?

Just the ones that popped up in my head as I was writing this:

Europa Universalis IV
Majesty: The Fantasy Kingdom Sim
System Shock 2
Pillars of Eternity
Planescape: Torment
I have no Mouth, and I must scream
The Legend of Grimrock series
MYST
Hollow Knight
Thief: The Dark Project (I think the non-gold version is better... The gold version has some levels that I really don't enjoy)
Unity of Command

Dota 2
Pubg
Csgo
Gta5
Starbound
Bioshock
