I can see why the studios are crapping themselves. No longer are they competing on mere copying, now they are competing on creativity!
Seriously, if fans can do this with Star Trek, I wonder if they should take the central precepts of Star Trek, make their own entirely seperate universe and to hell with it - the studios who refuse to continue much loved series can be cut out entirely and fans can make their own series.
In fact, they could make their own series but have a central authority to allow for basic continuity but maximise creativity. Now that would be remarkable.
The fans could find their own games and spinoffs pretty nicely too.
