Doom 

A classic first-person shooter (FPS) made by ID Software, the same folks who made quality games like Wolfenstein and Quake.

When playing Doom, watch out for the Cyberdemon, for his rocket-launcher arm can easily kill you.

doom 

A game which all players of Counter-Strike, Halo, Quake et al should thank for making the first-person shooter genre what it is today.

Doom is a classic in the true sense of the word. It spawned techniques still used in First-Person Shooters today.

Doom >is greater than> CS+HL+Halo+Quake+Unreal+GoldenEye

All are fantastic games, but Doom outranks them all. After all, Doom is simply legendary among shooter fans, even more so than the seminal CS. Thank Doom, with its crude 2D sprites, blocky graphics and unparalleled gameplay.

Doom 

One of the greatest FPS of all time. While the game may look outdated today, the gameplay is unparalleled even today. The game plays incredibly well even nowadays. Most fanboys/fags say it sucks because the graphics are bad, but in that case, they need to fuck themselves. Gameplay > graphics.

Halo faggot: omg omg omgomgom Doom sucks halo is BETATAT!!!!1
Normal person: You fail it. Without Doom, Halo would have never existed, so suck your boyfriend's cock and chill out.
