tinyE: Would you consider it a waste of time to build anything on the planet to make room until you can upgrade the ship?
And again, is there a plot other than just buzzing around the universe? :P
You probably figured all that out by now, but I'm bored at work so I'll answer anyway ^^
You can have a nice planetside base, put a flag on it (they're used as teleport beacons), and then return to the base anytime even if you're half a galaxy away, so I wouldn't call it useless even once the ship is big. Especially since you can attract settlers to your buildings.
And there is a plot with story missions, so there is a point, even if I don't find it THAT interesting and prefer to just mess around and explore
Nice game, even though I prefer Terraria (the lack of an automap and of a pause is really annoying, and ironically I don't find exploration as fu in this one. Even with all those planets, it does feel a little empty compared with the biomes and extensive cave systems of its elder. I don't get as excited about "knowing the place and going to see what's just around the corner" as I was in T. Maybe I'm jaded?)
(Oh, and I'm a giant pussy too. It was irritating to starve every time I went away from the keyboard for 5 minutes, especially combined with the lack of a proper pause)
