No current metal band matches up to Justin Bieber's albums sales-wise. What's your point? Also, the Gran Turismo is similar to the Halo series in sales, and it's a PlayStation exclusive title. Also, since when do sales dictate what is "better"? Are you saying that Mario is the best video game franchise in the world? As far as I know, nothing even comes close to passing Mario and its off-series games in franchise sales. Get real, guy. Halo is good, and I'm not denying that. I'm just saying that PlayStation has great exclusives planned and released. Xbox has only ever really had Halo, and this is coming from somebody who used to play Xbox and PlayStation. That has always been their "thing". Titanfall was supposed to add to the lineup, but we all know how well that turned out...
