We will probably do that, after my Univ. exams are over and I discuss with the team, we will decide if we can release something, and clearly stating that we won't continue the project. But some maps and skins i think it falls to the 'fair use' section of the copyright.
On the Chrono License talk, first i think SE wouldn't sell it to anyone, second I think if the sum was large and SE considered selling it, they would only sell to a company and ask them royalties for each copy sold, and third, i know this is just a dream, but if we could really buy the CT license i think we would have to raise the bar to SE standards.
