Starbound looks pretty promising. I'm glad they're trying to let everyone know what's going on and how much closer we are to getting a Beta release. The development team are also really cool people to talk to and they stream from time to time (Mainly Bartwe but I managed to help persuade Kyren and i'm trying to get Rho to show some of her art skills ;o).
It's one of the few games i'm hyped for this year~ And Cubeworld but Wollay takes his time perfecting things.
