Very fun and easy-to-get-into rail shooter. Love the dialogue between the Starfox crew and really appreciate the open-ended nature of the levels. It was very rewarding discovering the requirements for moving onto certain planets, based on how you perform on what level and what you do in it. The short length also helps make it replayable.
This is a game designed to be mastered. Something this short, and with this kind of replay value needs to be extremely fun and have a high enough skill ceiling in order to succeed. Star Fox 64 has those elements in spades. For years I have, on a whim, slapped Star Fox into my N64 and knocked out a quick run in a couple hours, and I never get tired of it.
