Hi, i wanted to buy no man sky with my friends but we have a question

what update did gog come to? on steam currently the version is "the vision" on January 31, on gog what version is it?

how does multiplayer work at the moment? and generally, what are the differences between the steam and gog version?

Same version as Steam (1.77). Multiplayer, from what I understand, works fine (I haven't tried it though), but be aware that there's no Crossplay between Steam and GOG, so if you have friends with the Steam version, you won't be able to play with them. Other than that, there aren't any differences between the Steam and GOG versions.
