I wanted to see if I could create a startup video in the same style as the Nintendo GameCube intro and here's what I came up with. It's 60 seconds long, but the main animation is only around 6 seconds, which makes the rest of the animation a loading screen.
I also made another version of this startup with a remixed GameCube intro song so depending on your preference you might want this one or the remixed one. I don't want to spam the forum with essentially the same video so I included the link to the second version of this startup in the description box of this video if you want to see it.
Edit: Added a 4:3 aspect ratio version.
