There are some other differences between my figures and those that EA showed, and I have some theories about those. Consider the case of Activision, which earned a 66 percent in the EA chart and a 62 percent in mine. First, Metacritic has some different review information from GameRankings, so it is possible that one site or the other is missing some reviews. Second, I considered games with as few as 1 review score; one could certainly take issue with that, since it will generally drag down publishers of low-visibility licensed games. Finally, it isn't clear whether EA included all of a publisher's subsidiaries, like the Activision Value division of Activision. I took the time to group these subsidiaries into the average for the larger publisher, thus Activision Value got included with Activision, Global Star Software got included with Take Two Interactive, and so on.
