Assault one is best, but I'll also say that while the multiplayer of Assault is great, it is a bit unbalanced. I noticed this when 1v3's were easy for the 1 to win against. Like, really easy
...but nuts and bolts was a spin-off
....and how can a game be disappointing if you enjoy it (Well I Guess there's some ways but still)
Very debatable, plus the gameplay of the games are different. SF64 is a lot of flying sections; Assault mixes it up a lot. Both games (Asides from a few buckers in 64 and MISSION 9 IN ASSAULT) are fantastic.
Varied vs Unvaried
Pick your Poison.
...Except all the Assault boss battles were interesting and each had their own unique flavor.
I disagree. Highly.

Assault at least has an equal soundtrack, and the composer behind Assault is generally better.
I'll go subjective on the rest but really now? 64's story was basically the same rehashed story (Though told well in the intro) that's happened over and over again. Father's killed, son takes place, war ensues, and nothing else. Assault is pretty developed (Even if it gives some parts away) althrough the story.
I spent ten hours 100%ing it and got close to 100% on the 3DS version while getting 100% on every other Star Fox game in the past 2 years. I actually did Assault for a Let's Play, so I know it's flaws. I know how riggid the ground combat can be at times, or how ****ed up the glitches you can do with the landmaster are, so I'm not being completely biased. Sure, it may overall be the better game, but 64 still has many great things about it (Esp after the remake) and Adventures is still a great game. Plus there's Star Fox 2.
Mostly good from what I skimmed but 20 hours? You know how much it costs just to make a game that lasts 20 hours, right?
One game can't kill a series or else many series would be dead.
Believe me when I say that. MANY.
Command still sold decently. Sure it's the worst and most breakable in the series, but it sold fine.
Let's keep hoping for SF Wii U.
