Doesn't look good.
http://www.fireflyfans.net/mthread.aspx?tid=60304And this from Wikipedia:
"While the game was originally planned for launch in Spring 2015, the developers were required to recreate large amounts of it after the original show's cast were brought on to provide voice acting. John O'Neill, CEO of Spark Plug Games, said that they were having to "change everything" and that they were deliberately not providing development updates to avoid "saying something that’s wrong again."[16] Unfortunately, the last time anyone heard anything from Firefly Online's Facebook page was March 2016, with the message "We're still here. We're still flyin'. Game is still in development. Stay tuned."[17] To the contrary, given that neither further news nor an explanation for the lack of further news have been produced ever since then, the majority of fans' believe that the game is no longer in development."
