Star Control 2 were a great game. As a gift to fans, creators released the source code. The Ur-Quan masters, a free port of it to newer windows with voice acting and stuff were made. People have also modded it ALOT.
This is an example what a company can do to amuse their fans.

JJ2 creators may someday release it When it's done. Then there might be some people to remake JJ2 to new glory.
But if JJ comes to Xbox live arcade, I think it wont be released before that...

Excuse me for this random reply, wich I felt to write... ^^'
