A new If I Were a Captain trailer offers a first look at gameplay from Firefly Online, the upcoming Unity-engine MMOG based on Firefly, the cult-favorite science fiction series. The accompanying description indicates they are accepting signups for the game, but that demand overwhelmed their host, and they are in the midst of transitioning everything to Amazon, so none of the included signup links work for now. Here's the refresher they offer on plans for the game: "Players take on the role of a ship captain as they hire a crew and lead missions, while trading with and competing against millions of other players like themselves. Much like the crew of Serenity, the Firefly-class transport ship featured in the original show, players must do whatever it takes to survive in the Verse: find a crew, find a job and keep flying."
