The reason I think we should make it mandatory that all people that contribute to this book to agree that there works will be licensed under CC0 and must also be uploaded to the internet archive under CC0 license is so that the book could be free as in freedom http://questioncopyright.org/how_to_free_your_work That way if Namco want to use stuff from the book they will legally be able to do so.
Well, Klonoa is a character owned by Namco - and not under CC0 License at all
. Thus, all fanworks based on Klonoa shall be considered as Namco's intellectual properties without a doubt. It's Namco's right to use any stuff from the book at their ease. As for OCs, things might be in a legal gray zone, however; Namco can always contact the artists first, right? Would a fan who even made a Klonoa OC doesn't want to help with the next Klonoa game?
If you really, really want to have the Klonoa series go CC0 License - you should ask Namco directly, not any one of the Klonoa fans.
For that we need the book to be licensed under Creative Commons CC0 license
Again, ka64 have told you the book will be non-profit. So we don't need to worry about the copyright issues.
Can we keep the thread sticking to the topic, please?
