As Erik said, who publishes it makes all the difference.
Using the Nintendo example above, what is the difference between your 2nd and 3rd parties? Who actually published the game.
If N makes and publishes the game, thats 1st party.
If N only publishes the game and some other company is in someway owned by Nintendo makes it, thats a 2nd party game.
**Normally, these two are pretty much considered the same thing. As N is still chief and the games are exclusives.
If N has nothing to do with the creation or publishing of the game and is merely collecting license fees. That is 3rd party.
**This is where N has failed the last two generations and due to the extreme success of the Wii will fare a billion times better now.
