I'm weary of the Sean Murray hate.
I don't know where the line is between "lie" and "overpromise." If you say you'll do something, and you fulfill your promise later than expected, have you lied? The charitable interpretation is that Hello Games intended multiplayer for No Man's Sky and eventually delivered the feature. If you believe their roadmap, they're about to expand on it.
The free updates have been incredible, there's a VR mode (that some have already played, it's not vaporware), and the game is endlessly engaging for a certain type of person. It's not for everyone.
Sean Murray never explicitly said "I'm sorry," but
he did own up: "Whilst I couldn’t be prouder of the team, I personally made mistakes." Not the weaselly "mistakes were made," but "I personally made mistakes."
I wish some of you could find it in yourselves to let it go.
