What was so bad about the Pac Man Vs clip?

That game is awesome by the way. It is really fun with four players.

 

Its not so much the clip itself, its the fact that Pacman and Zelda 4 Swords was Nintendo's "Megaton" games for that year.

Mario Kart: DD came out in November 2003.  Didn't they show it at E3?  Zelda: Windwaker also came out that year, but early in the year, so it was probably before E3.
