Yeah, definitely - I loved Star Fox 64 too. I just wonder if anything has prevented them from releasing Star Fox 2 since. I think the repro carts out there show that people would buy it if released in some form.
I also agree the sequels after 64 have been pretty lackluster, although I do really like Star Fox Adventures (partly because it's old school Rare), but I consider it more of a side series, like Mario Tennis is to Super Mario World.
