Not that you haven't heard it a million times from me, but I strongly endorse the avenue of approach being attacking Team Ninja directly. Pressuring them into releasing a stronger game resulted in DOA 5, which yielded the explosion of growth we saw in a post DOA 4 world. That -can- happen again.
I have a much different view of it. A lot of devs think they have to make their game unique for the sake of being unique, even if their ideas are bad. It's the reason we can't get anything in DOA fixed.
