There was an article on HN recently about how many people (esp. young people) have a different idea about copyright from the law, and seem to think that so long as you attribute something, and especially if it's not taking sales away, then it's OK. That is one idea of copyright, the law has a different idea.

In short, the Command and Conquer trademark is still in use, so EA are legally required to sue you.

The copyright on the art work is fully covered or for the next 50 years (or maybe more).

It doesn't matter if the company doesn't exist anymore (their assets, incl. IP) belong to someone. It doesn't matter if a copyrighted content is not being commerical exploited anymore, it's still copyright.

If this sounds outragous to you, talk to your politicans, read Free Culture by Lessig, talk to a Pirate Party.
