The Official PlayStation 3 Exclusives list...

[Torillian]

Well I think I would agree with you, if the thread was meant to be about 3rd party exclusives, but that's not what the thread is for. A game being first party doesn't make something any less exclusive, it just makes its exclusivity obvious. A list of those games is still useful though because not everyone is aware of what all the first party developers are making at any given time.

Certainly a list of 3rd party exclusives would be more useful for gaging the health of developer interest in the platform, but I don't think that was the main purpose of this thread.
