You are making the assumption that after all those years - Marvel shut the game down?
Based on what Voodoo?
corporate lawyer voodoo mixed with NCSoft deciding to not spend the money to actually defend CoH in court. yeah, they know good and well that they could have easily defended CoH against Marvel's allegations but marvel knew that they could drag out the court process and cost NCSoft millions more than the game would be worth in the process, so NCSoft took a settlement.
at least thats the cause and effect I would think could lead to a shut down.
what kind of case would stretch on so long that NCSoft would get tired of it? the kind where marvel brings up one accusation in each hearing as evidence that CoH infringes on it's character IPs. a never ending onslaught of "that character looks alot like hulk, and we saw some players with a wolvarine look-a-like.
baseless unprovable accusations, but also non-disprovable. or at least thats how NCSoft's legal department advised them, tht the case would go on for years costing them millions more than the game makes on average. A never ending hearing.
thats why NCSoft wont fight back and why if we want to fight back we need to plan carefully, we need to find out what the base of all thier accusations are and attempt to prove that such concepts that they note are not individually owned by thier company alone but are used by countless characters from all sorts of series. once that is brought to the courts attention your should call that an 'article' and give it a number, that way if Marvel tries to say something different like "stateman's star and coloring is too similar to captain america's shield" you can say "objection, article 5, stars and stripes are the symbol of america and multiple other nations and states the concept of them cannot be owned by any one company in specific."
I have been informed that I am missing something big in my whole 'ncsoft was shut down' thread, so I'll incorporate it when I hear it.
