Awesome. Please be our lawyer. RtKHeaven is not indexed by google, so please give us another example.
Still, you said 'unless KOEI has come to you', so it means even our action is legal, we still have to listen to the owner of the art (KOEI) if they want us to remove the art?
Let me ask Gun Urra just in case: are you by any chance from KOEI?
Well no i dont work for Koei, lol.
What i meant about Koei not complaining to you, is that they wont complain to you at all. You are not doing anything illegal by using those pictures, you are re-distributing them for a fee or claiming copy right on them or anything. So even if you got a email from someone high up at Koei telling you to stop using artwork that was featured in one of there games, you would have no legal obligation to agree to them.
Koei will not mind regardless, there mission statement about the Dynasty Warriors/Three Kingdoms games is that they want the west to learn more about Chinese history, and since your helping them with that, i think they'll thank you if anything.
btw i found another website that has alot of the game resources available for download.
