Doom 3 barely gets a recommendation, the BFG edition I would skip: Flashlight being an essential part of the early experience.

A departure from the old (and new) gameplay, leans more into horror. Horror works to some extent as the flashlight mechanic does bring it's own anxiety to the gameplay. Once the game advances it becomes apparent that the game is torn between the old doom and the new, slow, horror based Doom. This creates an odd balance, where the game seems like it wants you to go slow with a flashlight, while shooting demons with a rocket launcher. They should have just picked one and stuck with it. Blasting demons is still fun, though.

Environment progression during the game is well made and fun to experience. Though the game could have been shorter. Mostly due to how repetitive it becomes. Most of the enemies are the same, and even the encounters start to repeat after the first two levels. If you see an imp spawn in front of you, you can be sure another one spawns behind you. This repetitive nature of combat encounters gets boring fast. After the first hour of gameplay you have experienced most of what the games combat offers.

Weapons are okay, but they lack any sort of character. Sound design on the weapons is poor and they all lack impact. Sound in general seems like it has the dynamics made for some 2€ PC speakers from the 90s.

theres a doom game for everyone: this one is for people who like horror shooters

still the best DOOM game, although i wish they stuck with the original demon designs
