Well I'd like to add-on to what makingmusic said above, keeping bias is great, it shows your dedicated support to your console :) which is great! But don't bash another console, like I'm a serious Sony fan, but I try to avoid talking about the 360 or the Wii unless I have something positive to say.

That said, stick to the topics :P Some of the Wii fanboys around here bug the living Sh*t out of me when we start a thread on PS3 games, then along comes a troll and starts talking about how AMAZING their Wii games are in a Fcking PS3 thread ><. It's not a Wii thread, obviously we don't care about how amazing Wii games are, as long as you stick to the topic, don't bash, and attempt to keep an open mind, you'll be all right :P 

its okay to have a favorite--the problem comes when you go to the next level and become a Kber---hahaha--Jk--

 Yeah many of us have had our little outbreaks, myself included, but with the sites current scale of fanboys I see it the most from Wii owners sadly :/ Of course the Sony fans have to sit and watch when some of our more profound trolls go on a ramapge XD /sigh

Having a favourite is fine, but that doesn't make your console of choice the best in the world. That's what a few people in here are struggling to fathom, it seems. Remember to respect other peoples opinion even though it might be the direct opposite of your own, and don't call people ignorant or fanboys/girls for not liking your console the best.
All our preferences are based on many factors, and bashing someone won't change that.

Having a favourite or bia towards consoles is fine, thinking that your console is the best in the world is also fine.

This is fine as long as you repect the other console and people opinion. For opinion put "in my opinion" and for fact just put as it is.

If someone say something in their opinion that your don't like, don't bother about them.
