It's the consumer's fault in so much as it is blinkered naivety and selective retention of information about the game. There are interviews where Sean Murray talks about multiplayer (and yes he did not help in the slightest with the overhype of the game, there are of course things to criticise). There are also multiple articles pre-release with titles like "Stop Thinking Of No Man's Sky As A Multiplayer Game", "'No Man's Sky' Is Effectively A Single Player Experience", and "No Man's Sky 'Is Not a Multiplayer Game,' Hello Games Founder Says". The final press release pre-release (
What do you do in No Man's Sky?) lays out quite accurately what the game actually is. There is no mention of multiplayer. It explicitly states:
That means this maybe isn’t the game you *imagined* from those trailers. If you hoped for things like pvp multiplayer or city building, piloting freighters, or building civilisations… that isn’t what NMS is.
There were never any previews showing any traditional multiplayer. There was never even any concrete laying out of what said multiplayer would entail. There should be and element of cynicism in watching any developer interview for a game currently in development - it should be accepted that something said in an interview might not make it into the final game, by development's very nature. But more importantly, if there have been multiple sources around the game, including a pre-release press release and series of tweets from the lead dev, citing it is not a multiplayer game and that people should not go into it expecting a multiplayer game, then I can't really sympathise with people who then bought the game expecting it to be a multiplayer game. It's also very very easy to just wait for the game to come out and read some reviews before committing to a purchase, especially when it was unclear for much of the build up to release what exactly the game would entail.
I was following the release very closely and the game was pretty close to the experience I imagined it would be. I certainly wasn't expecting traditional multiplayer when I bought it. I don't think that's because I am some sort of prophetic genius who saw through a layer of false expectations and misadvertisement. I think it's probably because I actually looked into what the game was rather than just buying into the insane hype.
