jarrod, that would be true if the case study was of the industry as a whole. but a vertical slice, and one taken from the very best the industry has to offer, is an accurate representation of a bias in review score. i wonder if i could use this info to create an equation that could guess edges next score lol.
however aragod I believe you should take a vertical slice from a development perspective. for example only use first(possibly 2nd) party studies games from sony and microsoft compared to multiplatform games.
anyway , good read.
