> My new graphics are dual licensed as "GPLv2 or later" or CC-by-sa-3.0 Why do you chose the license "GPLv2 or later" for art? I can see a point because I've heard people say that even art can be licensed under the GPL v2 or v3 (maybe even v1, I don't know). I also know that the starfighter software is under the "GPLv2 or later" .
