Firefly Online (FFO) is a multi-user, social online role-playing game that will initially be available for smartphones and tablets, including those based on iOS and Android operating systems.
The Trailer doesn't show much of anything except for the title of the game. I liked Firefly and the movie Serenity.. I'm not certain I'll care for a smartphone game though. I doubt it will ever get as popular as Angry Birds, but it could still be fun if its done right.
