I mean, we got HλLF-LIFE², DOOM³, Far-Cry, Prey, F.E.A.R., Quake 4, Halo 2, and a whole host of other heavy hitters
the art style of most of these is probably my favorite of any video game (video that explains "the art style")
a lot of the best of those games were very well written
and the gameplay holds up to this very day
DOOM³ is probably my favorite DOOM game
HλLF-LIFE² is literally perfect
Quake 4 is... the only Quake I've played
and F.E.A.R. has an amazing aesthetic (yes, I know it's just the 2000s greys, but idc) and it has one of the best shotguns EVER
and Prey has that awesome intro
