Just came here to say (I don't have much else to add): You're drawing a big sweeping brush over the phrase "first party". You seem to have included first party + second party + third party games here. Do you perhaps mean "exclusives" instead?
Mainly referring to the inclusion of both Professor Layton & Ace Attorney. I mean, fair enough, outsourced-but-wholly-owned games like Starhawk & Luigi's Mansion I can understand, but what involvement does Nintendo have in PL & AA other than a publishing deal in certain parts of the world?
