People who hate on things that they haven't experienced first-hand.
For instance, people who hate Modern Warfare 3 because "ololol, it's a brown shooter that's just a map pack of Modern Warfare!!!!11!!" No. Shut it. I've played the campaign (I know, right?) and it's not just "a map pack". They (GASP!) put some thought into the story! Yes, it's essentially the game version of a Hollywood summer action flick. Yeah, the game-play isn't that much different because seriously, how much can you change in the game-play mechanics of a modern military shooter? But it's got way more colors than brown-gray, it put effort into incorporating single-player elements, and it's a very tight and well-designed shooter. Though I can't speak for the multi-player because I don't are about multi-player. (Plus, they overhauled the sound of the gunfire so shooting in Modern Warfare 3 felt immensely more satisfying than shooting in Modern Warfare 2.)
Also people who act superior for liking something you don't like, or for not liking something a lot of other people like.
Oh, and tied in with that Call of Duty paragraph, people who won't buy a game if it doesn't have multi-player. Come on. You have
Killzone
Gears of War
Halo
Call of Duty
Battlefield
TF2
Resistance (I'd argue that one shouldn't have had it either, but all three installments have had multi-player).
Are you really going to care about the multi-player in Bioshock, Dead Space, Bulletstorm, Crysis, Red Faction, F.E.A.R., Call of Juarez, Warhammer 40k, Dead Island, RAGE, Uncharted, Saints Row, Serious Sam, Mass Effect, Syndicate (which most fans of the original don't care about anyway), Max Payne, Aliens: Colonial Marines, SOCOM 4, Metro: Last Light, Section 8, Splinter Cell, Rainbow Six, Metal Gear Solid, Ghost Recon, Lost Planet, and Singularity?
EDIT: I encourage co-op campaign multi-player though. Bonus points if it includes local co-op.
Extra EDIT: Oh, I also hate it when NPCs in video games are unkillable.
