Came to say what everyone has said already. We've been waiting nearly a quarter century for another Star Fox game that isn't bullshit in some way. Every game after 64 has to come with some stupid ass gameplay or gimmick that tricks the entire package off in some form or another.
Start with Star Fox 64, and then end it there after that. If you have a Wii U, you can give SF0 a try. Some people don't mind it, but most hate it for the forced Wii U GamePad integration.
