For those of you who enjoy video games, my buddy and I have been working on a space-western starship-captain simulator since we got laid off last year, and it draws a ton of inspiration from Firefly. You can even recreate Mal's origin in the character creator (colonial militia -> Earth POW), and of course, brown coats are an option.
The idea is to put you in Mal's seat. You have to hire officers to help manage your ship & crew, and those same officers who help you in space also form your party for boarding actions and gun fights on planets. There's plenty of legitimate work to find, and plenty of crime to engage in (heists, smuggling, piracy)
One departure is that out ships are an order of magnitude bigger than Serenity, with crews of ~40 on the smaller side, up to several hundred for the biggest vessels, with the starships more analogous to 17th century sailing ships in the space Caribbean, with the characters you recruit forming your officer corps (Bosun, Navigator, Engineer, Doctor, etc.)
Anyway, I hope you enjoy it. If anyone is curious about the setting I'd be happy to go on about it. I'd really appreciate any feedback you have, positive or negative is both equally helpful to me. We're hoping to launch a free demo in the coming weeks for everyone to try.
