How come if you don't like an exclusive title you are automatically biased?

It seems to me you just don't like B-tier games. At least, your 360 & PS3 list seems heavily populated with them.

Which is almost the exact opposite of my preference in games. I tend to like the slightly-lower budget stuff and am not such a fan of the AAA games. I've never been called out for being biased for disliking Gran Turismo, Forza, Killzone or Gears, though!

Perhaps it's something more to do with your attitude. But I don't really know what the answer to your question is.  Kinda mostly drifted off-topic with this post, whoops.

Yeah I tend not to like B-tier games. Although I do like some.  

P.S. I like all the title you mentioned.

Here is another question for everybody.  A few people might know what Im talking about on this.  I like Forza more than GT so if I say that im a MSFT fan.  Same thing goes to me if I say i like InFamous more than Crackdown.  And for a while more than Prototype.  For whatever reason Xbox fans was associated with Prototype.  So when i said I though InFamous was better people automattically thought I was sony Biased.  This goes on and on with whatever two title you say that are exclusive.  

But then when I say I like CoD more than Battlefield there is no harm no foul.  I mean people might say that im wrong but i dont get called biased for it.  Why is this only associated with exclusive titles?  And why can't people like something more than something else and say it?
