Halo : Reach is the 4th Halo game on Xbox. The only reason why Halo 3 sold so much more than other Halo games is because it was the FIRST Halo game on Xbox. 1st Halo game on Xbox 720 has a chance of outselling Halo 3 though

great... so how do you explain COD increasing sales from MW1 to MW2?

 

Or Uncharted 2 from Uncharted 1 for that matter.

Uncharted 2 not being a new IP anymore like Uncharted 1?
