Depends what you are after. The game is certainly incomparably better to its initial state on release. Smoother, prettier, more complete. Has missions, exocrafts, base building and more.
However, the basic gameplay has not changed much, except for it being smoother. It’s a resource gathering, building, moving on loop.
I spent about 40 hours in total in the past and I just started a new save using the option that is called explorer or something, that basically has no resource requirements for building stuff. And I am enjoying it, since it has removed the tedium and I can simply use the game as a playground for finding interesting looking planets and take screenshots, and generally have fun.
Other people’s mileage may vary, of course. But if you’ve never played the game, at its current state I would say give it a try. It’s is definitely interesting.
