There was only 3, Guitar Hero from Activision at No.8, We Ski from Namco Bandai at No.13, Game Party at No.17. Considering it was We Ski and Game Party's first month and they achieved probably on the wrong side of 100k, and the only other game is Guitar Hero, i would say that as a whole the Wii's software dominance is almost entirely through first party. Very few third party games have sold in large numbers on the Wii so far and none have achieved numbers any where near those Nintendo first party have.
