@beardalaxy The only other Star Fox game I played was Command but that is a completely different beast and that game had all range battles and a turn-based strategy element. However, I was only eight when I played it and I could never beat a single level. My older brother played it the most (and he grew up with SF64).
RS was linear in terms of level progression, last time I checked. There are a few bonus missions but that's about it. I think the ability to replay missions and unlock more ships makes up for it though.
Rogue Squadron's music was awesome because Factor 5 wrote their own sound drivers for the game. They pretty much rewrote the N64s firmware which is why it is impossible to emulate that game.
And this maybe an unpopular opinion, but if Nintendo is really finding new ways to innovate the Star Fox franchise, I wouldn't mind them trying to experiment with a Rogue Squadron or Ace Combat style Star Fox game. I wouldn't think it would be too big of a departure like Command was.
