Everyone says this and I really disagree. It's been a year or so since I last play but I have been playing off and on about every year.
Whenever I start a new game, it feels basically the same. Once I get into the universe, there are way more things to do but nome of them feel like they matter.
The game is a classic example of a mile wide and an inch deep. Every update just seems to bring a new system that feels, in itself, feels about as satisfying as the game did on launch.
Despite the valiant and admirable effort to continue updating the game (and for free), I still don't think it's come close to the game that was promised. It's still the launch game in my eyes; nothing seems to matter. I can just also build a base (or any of the other new features) that doesn't matter too.
It's a fun game for maybe 30 hours a year (300 hours!) and that's an accomplishment but I don't think it's come close to fulfilling it's original promise.
