It’s actually particularly bad for Hello Games from a marketing perspective, as this was the main factor which doomed their last game. The way they spoke about “No Man’s Sky” set some expectations in fans’ minds, and when the studio failed to live up to them, everyone started picking the studio’s claims apart and mocking them openly.
According to some, the only way for Hello Games to ever properly recover from this situation and get another shot at a good release is to be very open and straightforward about their development process in the future.
This means releasing raw gameplay footage and guaranteeing that it’s such, as well as being more direct and accessible when talking about planned features of the game.
For example, one of the main controversial points about “No Man’s Sky” was the developers’ implication that the game is going to feature multiplayer. The final result was completely different, as there is no possibility for players to meet each other.
Avoiding outright lies like this would be a first good step. But the studio still has a lot to think about before they even get to that point. They shouldn’t be thinking about a new game right now when they still have a lot of work to do on “No Man’s Sky”. The game might have gotten lots of refund requests, but there are still some people who keep playing it and would probably appreciate some additional post-release support.
