As much as I like Starfox Adventures, and while some of the areas/puzzles have made it basically untouched, Dinosaur Planet in this form seems a whole lot more simplistic, barren, and drab than SFA, and appears like there was still *alot* of work to be done still.
There is so much of that video being a character just running around big empty areas with really nothing to do but fight a generic baddie once in a while, or just looking for the next key. The pacing is just dull and everything seems to move so slow. I don't know how far from completion this was, but I will say the end-result in SFA is much, much better. It's like they figured out every aspect in this video that was somehow lacking, including even the music, and tweaked it immensely for SFA. It also looks like they took the abilities from both characters and sorta merged them into one, making Fox a much more "complete" character.
