1. Excluding or tending to exclude: exclusive barriers.
6. Not including the specified extremes or limits, but only the area between them: 20-25, exclusive; that is, 21, 22, 23 and 24.
7. Excluding some or most, as from membership or participation: an exclusive club.
It appears that even by definition exclusive does not just mean ONE AND ONLY ONE like you all seem to think!
So thank you for showing us that 360/PC exclusives are still exclusives because they meet all the above requirements from the definition.
And if you really want to be so overally picky just to save face for the PS3 line-up, why not do an "MS exlcusive vs Sony exclusive" thread since both PC and 360 game sales benefit Microsoft's platforms. It really is amazing how many PS3 fanboys don't realize they are helping Microsoft and going against their fanboyism by being PC gamers.
