Yup, and as far as Forge is concerned, it was done in Halo 3, in 2007. Along with File share, saved videos, and all the rest.
That was Halo 3. Reach has expanded on everything, including Firefight 2.0
MOH is going after the Modern Warfare brand, pretty much polishing up a few thing here and there. In other words. Even if it did top MW, its still just copy and paste with a few added bells and whistles. Reach on the other hand is expanding and adding on to the innovations of a 3 year old game which has yet to be topped in terms of features, and pumping it full of steroids.
Its basically an unfair argument lol, the 2 games are light years apart.
Just had to get that off my chest lol.
