I expect a lot of similarities are going to start filtering out as people play the game.  I noticed from one of the game magazine reviews that SCO has rainbow worlds where you can get access to lots of purple high value resources.

My IANAL is this in a vacuum isn't an infringement, but an example of riding UQM's coattails.  If the location of these worlds is valuable to the Melnorme Maelnum Maelnir and they form some pattern on the starmap, then things get progressively hinkier.
