I know im a little late with this, but Starbound is now avalible to Pre Purchase.
They have a system like Kickstarter where you can get extra perks for buying a different package.
All Packages come with Beta Access when the game enters Beta Stage, which should be relatively soon.
Grab a copy when you can and join us for some Epic Adventures in Space!
Also, enjoy the Teaser Character Creator to help get your mouth watering for this game.
We will have a GamerApoc Server running for this game similer to how we had the Terraria one and all members will be welcome to join us.
