Star Fox 2 was the original sequel to Star Fox, fully completed but never properly released. An unfinished prototype is floating around the web, but allegedly doesn't hold a candle to the finished product. This game contained many innovations and is all around very fun. I feel it's worth allowing the public to enjoy and see where many elements of Star Fox 64 and Star Fox Zero came from.

I understand that this may not be feasible due to legal issues (such as Argonaut being out of business), but I hope you can look into it if there's enough public demand for this game.
