It’s not playable, it’s a buggy mess. A $200 million buggy mess. CIG has never made a single deadline it’s set for itself.
They've switched to a quarterly release system and have, in fact, just released their Q4 drop last evening. I would grant you that they have had a history of missing deadlines, but stating that they have "never made a single deadline" is disingenuous at best.
Those issues were fixed in the 3.3 release earlier this year.
Last time I looked into SC (a few months ago), the only gameplay loop consisted of picking up cargo and dropping it off with no failure conditions attached. What else has been added since?
