What should be noted is that Garriott can't just make a game called Ultima, because EA will still own the trademark. For video games, copyright covers things like the source code and audiovisual elements, whereas the trademark is for things like the brand name, specific characters, things like that.

So, that's confusing, what exactly can be done when you have a copyright but not the trademark? Are there any examples of that happening before? What could you do with this that could not be done with a spiritual successor sort of game?
