Well, I guess I need to add another: Bungie's Halo. Yes, people biased in favour of Bungie's tenure on the Halo series. Why? Because sure, Bungie's tenure is better than the hit-or-miss tenure of Halo Studios, aka. 343i, but they have let their love of Bungie's Halo blind them to the truth: That Bungie were also fallible, that their Halo games weren't perfect masterpieces, and that the Bungie they worship have long since gone in favour of a bunch of corpo-rats who are in the midst of turning their IP into an extraction shooter. And because they're so blind, they spend most of their time ranting and raving about how "343 INDUSTRIES KILLED THE SERIES!", attack people who like Halo Studios' outings and make up stuff about how "They hired people who HATE HALO!!!111".
Too much hatred for something can be just as annoying as the thing that's being hated on, and Bungie Stans are a prime example of this. Want proof? Look at any of the threads here involving Halo: Campaign Evolved. They are full of Bungie Stans displaying this behaviour.
