In all honestly, probably Starbound.
The game's fun, i guess, sometimes, if you mod it and it works, but the devs are like a bunch of goddamn 12 year olds who never grew up. They have their heads way in the clouds with too many idea guys and nobody to reign them back in and focus and as a result the game has stagnated and suffered delay after delay after delay. Their latest dev post about ship AIs just takes the cake for pathetic and childish, displaying an AI avatar for what's supposed to be a medieval-themed race as a busty woman in the memehorse mask reciting the fresh prince of bel air opening. Naturally, some people realized how absolutely handicapped that is and called them out in the post's thread on the official forums, only for moderators to lock it because it's getting "off topic".
Seriously. They're loving children.
