The reason it "doesn't count" is if Jim has a good PC.
For someone like myself who has a rather beastly PC: Choosing a 360 is rather foolish compared to the exclusives found on the PS3.
Not only is the 360/PC games available for me on the PC but they are also better due to the hardware being newer as well as them at.. times.. being.. free (Pirates.. derp)
Walking around here in Scandanavia and you'll see barely anyone calling a 360/PC game for exclusive due to the fact that so many of us are PC oriented.
