Taken from various posts in this thread:

10. Splinter Cell Conviction

I'm sure there are others, but I stopped counting, and to these I say:

I have played most or all of these games on a non-360 platform -- at a cheaper price than on the 360, with better graphics, and with free online. I will continue pointing this out in every thread I ever see of this nature (i.e. any thread talking about 360 "exclusives") until you stop pretending these are exclusives because it makes you feel better in this console war. No, putting "console exclusive" doesn't make it better. If I said FFXIII was a "PS3 exclusive," you would bitch and moan, even if I reminded you that the PS3 is the only system called PS3 that has FFXIII. It's an obvious attempt to circumvent the very idea of an "exclusive" title. Not only can one play these on a different version, it is typically true that the 360 version is the inferior one by virtually any objective metric.

Yeah totally. I'm like one of those annoying Climate Scientists that keeps bringing up Global Warming, or one of those Political Scientists that keeps pointing out that there are no WMDs in Iraq and that our supposed premise for invading the country was false.

I mean, everybody knows, essentially, that they're right. But they're also super depressing. So can they just shut up already?

Wait, you were serious? If pointing out these games are on another platform counts as "console wars," then I didn't bring the console war in: it was already here.

Okay, let's imagine if I made a new thread, and started listing all the great PS3 exclusives like Lost Planet 2, Grand Theft Auto IV, and Final Fantasy XIII. I even titled the thread, "The PS3's best exclusives." If someone came in and pointed out that these games are actually available on other platforms, would you really blame the person who pointed out the inaccuracy for starting trouble? Obviously not. The person who started the thread started the problem.

That seems so obvious to me I just assumed you were joking.
