"Namco did a much better job of Starfox on the GC than Rare did for any except the original."
According to Metacritic, you are incorrect in your assessment. The Namco Star Fox game (Assault) received a cumulative score of 67, whereas the Rare Star Fox game received a cumulative score of 82. Ergo, Namco did not do a "much better job".
Also, what is up with everyone saying Rare sucks? They may not have released any great games (Viva Pinata excluded) recently like Battletoads, Goldeneye or Perfect Dark, but they do not "suck" as most people seem to purport. I think Kameo and PD Zero were above average games, and their most recent game for the X360 (Viva Pinata) was exquisite.
