GamesRadar - Doom 3 then. Too dark. Too claustrophobic. Too many corridors. Not enough carnage. Closet monsters, closet, monsters, closet monsters. And that torch-or-gun mechanic is cheap as hell. That’s the accepted wisdom of much of the internet these days. But you know what? Much of the internet is full of crap.

Doom 3 was id Software’s attempt at bringing back its slumbering franchise, and its arrival on PC met with critical praise back in 2005
A new Doom 3 mod paints the title with Doom Eternal's colors, inducing faster-paced gameplay and a variety of other gameplay enhancements.

Trying to decide the best DOOM game is like deciding who your favorite child is. You love every one of them, imperfections and all."
Awesome game.
Id recommend to any one who like this game that they give sikkmod a go. Really brings the game a few years up to date.
Overall I enjoyed doom 3. It had great combat and was a spectacularly sculpted experience. Yeah it got a little repetitive towards the end but I replayed it recently and I really appreciated playing a game that lasted longer than four hours. It's a good twenty-thirty hour single player experience. You rarely see that nowadays unless it's open world or rpg.
FYI
DOOM 3 and its expansion also came out for the original xbox. So if anyone is interested to give this baby a try, u can pick it up used and cheap and play it on the 360, which is backwards compatible :)
Doom 3+ expancion = best FPS/horror game... it's dam scary
