Top War sounds a little generic and uninspired, it was a placeholder after all.
After a giving it some thought I realized that a small flat circular object is not a top, but rather a disc. After tilting it a bit it looks even flatter than it should .
I could of course draw a line or a beam through the center of the image but that would be too easy. Instead I decided to declare the spinning objects to be discs. I thought disx sounds cool, after a while it turned into dizx and I though “I need to get a Y in there” so it became dyzx – seemed to be unique enough in google, especially in combination with “battle” it yelds no results, so I claimed it! :3
