X3: Non-playable Demo?

While the kneejerk reaction to this is obviously one of mild incredulity, I can see why Egosoft have chosen to release this "benchmarking" version of X3 as a demo. It must be remarkably frustrating for people who build wide-open, sandbox titles and then find they can't adequately promote or explain their game with a demo version. Perhaps there's no way to chop out a chunk of the universe for people to play, and there are obvious problems with putting out a time-limited version of a full game. I guess this keeps the download size down too. If you want to see how your machine renders Terran Conflict's pretty-pretty spacemobiles then you can get it here.
