You contradicted yourself. I said it WAS an exclusive, and the point was Sony IS losing all it's exclusives. MGS began as PS exclusives, then slowly went to other systems. My argument > your argument.
My point is still valid. No one is being angered. And you are wrong. The series started as a MSX game in 1987, then was remade for the NES, and eventually PlayStation got it's first MGS game in 1998. The sequel was then released sometime in 2001 IIRC with a remake being released on XBox, PS2, and PC in like 2002.
Only one game was exclusive to PS, which means that the "exclusivity" of MGS on PS only lasted roughly 2 years (Because MGS1 was remade and released to PC). The console "exclusivity" lasted roughly 4 years.
PS lost "exclusivity" as soon as other console became available.
