Chucklefish are set to start working on a second title alongside their current Early Access release, Starbound. The indie studio are proposing a new team of developers, so as to not hinder the progress of the Starbound team, and a completely new concept.
In the blog where the announcement was made, Finn "Tiy" Brice explained that they're mulling over a few ideas, but the one that keeps coming to the fore is "a top down, open world, multiplayer pirate game".
The post also includes an update on the progress and future of Starbound, so it's well worth a read if you're one the game's many early adopters.
