My favorite Star Fox is the original. I must have completed the game several times, going through each path, and even getting to the hidden areas like the giant slot machine. I don't always beat games I buy, but this one kept me playing enough to do so more than once. Also of note is that Slippy Toad in the original had a deeper 'voice' than that of Peppy Hare. Star Fox 64 was a nice 'upgrade' but while the 'tank' and 'sub' sections were ok, they weren't my favorite parts - which were flying the AR-Wing. Star Fox Adventure wasn't a true Star Fox game, it was RARE's cancelled Dinosaur Planet with a new character model. I have not played Assault, but from video reviews I've seen, less than half of the game really fits the series - the in-ship flying levels.
