Thanks, everybody! I've added toymailman and Questarian to the list!
Love the label, a little Imagic inspiration in there!
Absolutely, along with Atari's 5200 boxes and a few other ideas I mixed in. As I said in the thread about my gatefold boxes, I really wanted something with an appropriately contemporary look, but also something that looked like a third-party product, as opposed to mimicking the original Aquarius or Intellivision package designs. This is what I finally came up with, and I'll probably use this label design as a template for most of my subsequent cartridge releases. The nice thing about the colors is that the Aquarius logo already has a nice rainbow of colors inside the roundel, so those are the same colors I used for the stripes.
