UPDATE 9.30pm: Following this morning's news that the GOG.com version of No Man's Sky won't be getting the NEXT update's much-touted new multiplayer features until "later in the year", the retailer has announced that it's now offering refunds to those affected.
In a post on its website, GOG said, "We know that many of you expressed disappointment about the lack of the new multiplayer feature in the latest update to No Man's Sky on GOG.COM. While we have limited control over games and content updates, we want you to have the best and risk-free experience possible when you buy a game on GOG.COM."
GOG continued, "Although Hello Games chose not to offer refunds over missing game content to our users and instead promised to bring the missing multiplayer content later this year, we understand that some of you might not be willing to wait."
