As starbound is a sandbox game, building would be a very crucial element.Instead of building just square blocks like in Terraria,there could be slopes,triangles,and the ability to revolve these shapes with some gravity gun thingy?So you could actuall make a proper roof,combining different shapes to make a seamless building,not like those blocky awkward buildings like those in minecraft and Terraria.....maybe this...http://www.blockscape.com/v2/
To be honest, I don't think they will implement this, and I wouldn't want it either (but that's my personal opinion). I think it would make things too complicated, and I feel that the game doesn't need this either... Sorry...
Though it would look a bit better, I don't think this would be necessary since the real only use for shaped blocks is the roofs of ordinary houses. Which I sure as heck won't be building.
I think something like the stairs from minecraft would be fine, more types of stairs never hurt and they could go with a simple key to rotate. I don't see the point in triangles but slopes and regular blocks would be fine, I'm not sure what other shapes you're implying with "etc."
Honestly, I don't think we would need srairs, as the player already is able to walk up 1 block slopes anyways.
