If you can tolerate the potential character / universe restarts and such, the nightly unstable builds will make a true believer out of anyone. There's so much stuff that it's actually a little daunting to sort it all out a year after. It's not like Terraria where it comes out and "Oh, lol, there's fishing and a new tier of swords and an NPC that sells a bubble machine" and it's all very easy to sort through. I'm talking gobs of content piled on top of each other. Maybe it's the lack of documentation, but it feels like you sink neck-deep into Starbound content and it's easy to get lost in space (lulz).
i tried it briefly, but i had some issues getting the game running. must've chose a bad time. i didn't even get to the meat and potatoes, but i like how they changed the intro missions. it's not something you can just do quickly and leave the planet
