I honestly don't think I'm a fanboy of anything. I'm mentally running through all my favorite games, and I can easily admit that each of them have flaws. I mean, I love Uncharted, but the main character is kind of inconsistent douche. I love Mass Effect, but a lot of the elements of gameplay(Side quests, upgrades) are inconsistent at best, and still imperfect. I love God of War, but it's still very repetitive and the story only goes downhill from the first game. I love Bioshock, but hacking sucks and the vita-chambers aren't helping anyone. I even love Bioshock 2, even if the story is a bit of a mess and a lot of the new elements were poorly implemented. Need I go on?
No offense, but I think this topic is a little flawed. Liking a game doesn't make you a fanboy, it makes you a fan. Not being able to admit imperfection makes you a fanboy, and that's pretty damn rare.
