Not really. Nintendo helped bring it over here (GameStop also helped), but in Japan it's not first party. I wish this was an exclusive franchise from Ninty, but they can release Xenoblade Chronicles on PS3 or 360 if they wanted to. This game is just amazing.
Nintendo owns Monolith Soft so yes, it is a first party game. They also couldn't release it on the PS3 or 360.
Oh shiznit your'e right! It's cause I remembered Monolith Soft released games for the PS2, but apparently Nintendo owns them now. Welcome to the Nintendo family Xenoblade Chronicles! I hope this game gets an HD version on Wii U.
