Some have pointed out the number of Bricks (i.e.: including unreleased games, etc.) in this wall vs. those in some of the third party walls.
I'd like to point out that - perhaps - that's part of the reason why almost every title on Nintendo's wall is glory and the walls of these other publishers are shame. Perhaps, if they spent the same time/effort they do now, but on fewer titles, those titles would come out better.
I mean, seriously, the first Wii Guitar Hero game had ****ing sound issues. How the **** do you mess up the sound on a ****ing music game?
