I'm true to myself all the damn time. And I regularly name popular games/franchises that I simply am not a big fan of, never got into, or straight up dislike. For example:
Grand Theft Auto
Uncharted
God of War
Infamous
The Last of Us
Bioshock
Saint's Row
Gears of War
Resistance
Call of Duty
Halo
Far Cry
Metal Gear Solid
Resident Evil (everything from 4 onward)
The rebooted, so-called "Castlevania" games
Final Fantasy (everything from VII onward, with the exception of IX, which was decent)
Dead or Alive (I've always felt it was a poor man's Virtua Fighter)
the 3D Ninja Gaidens (Team Ninja in general kind of sucks at making things)
Oblivion (Skyrim, although the buggiest game I've ever played, was far better)
Battlefield
Dragon Age
Demon/Dark Souls
Killzone
Diablo
Starcraft
World of Warcraft (I liked WC 1-3, even though I didn't like the direction 3 was going in)
Assassin's Creed
And even when it comes to Nintendo published games, while I don't think I HATE any of them, there are series that I have just never gotten into, such as:
Pokemon
Animal Crossing
Professor Layton
Famicom/Advance Wars
1080 Snowboarding
Fire Emblem
Steel Diver
Mother/Earthbound
Custom Robo
Nintendogs, etc.
