chean: Not in because I already have it (and I don't have 20 rep anyway, heh) but +1 for the giveaway!
Redfern: I would be IN if it includes DRM-FREE builds (like Humble Store), but if no, then i pass.
chean: For the record, the Starbound currently available - it makes no difference if you buy from Steam or Humble - is DRM-free in the sense that you can launch it directly (using the actual exe/app within the SteamApps dir), i.e. without using the Steam client. You do need to launch Steam for the initial download and to get updates, however; the practicality of the latter being why they chose this path for this constant-patching stage of development, IIRC. Completely DRM-free (that is, fully independent of Steam) builds probably won't come until the later stages of the beta, and at the current rate I can't see that phase being reached before 2015.
Why its marked DRM-FREE on Humble then? I mean, usually that means that builds provided not tied to Steam in any way at all.
