This game got alot of flack because Chucklefish went silent for a while and people thought it was an abandoned project.
Turns out Chucklefish was just working too hard to bother making any wab updates, they started up again a couple months ago and there is now three update branches, Stable, Unstable and Nightly. Nightly is the most glitched, as it's updated every midnight, so play nightly at your own risk. I play Unstable and they just gave it an update, the addition of quests has changed the game quite a bit, there are now quests as opposed to just 'get this ore, build this thing, repeat'. You need to prgress so far in the quests to get to a new solar system. This game used to be like a bigger Terreria with less point, now it's finally turning into what was promised and Chucklefish is giving us regular updates again. They're introducing new bosses, I've only so far had to tangle with Dreadwing(the penguin UFO) and they haven't tweaked him much aside from give him a bazillion and three HP and he has his own level you can't build on. So while he's not that much harder, he's ♥♥♥♥ing hard.
If you got it and stopped playing give it another shot, I'm not sure if stable branch has been updated to the new quest system yet, though, I'm on unstable. If you don't have it and like sandbox tree punching sims definately give it a shot.
Hey Terreria fanboys, unless your crappy attempts at snarking can make me laugh like Sid1120's down there I'm deleting them. I'm sorry if this offends you. Also I accedently deleted a post from somebody who said Chucklefish was being 'condescending' to fans during the silence, didn't mean to, accedental double click. I didn't consider that a snark and can't comment on it as I was taking a haiatus until updates started again.
I was completely unprepared for so many votes... My second most popular review has one downvote.
