Get the half life 3 confirmed mug.IN MY OPINION...the best game ever. IN MY OPINION, it's better than Halo 2. Why you may ask? Let's list the reasons. 1. WAY better physics/graphics...2. Not nearly as many cheaters online...3. No douchebag ranking system...4. The gravity gun is just so damn cool. Now, you may say "Your only hating Halo because you suck." Not true, I'm fairly good, but I don't sit around and play it ALL DAY.
