Not much is known about the upcoming standalone multiplayer coming to Cyberpunk 2077. It's very much still unknown to us; however, CD Projekt Red has issued a few statements that they will not be "aggressive" when it comes to the use of microtransactions.
Microtransactions are never a good topic to bring to the table as a lot of gamers despise them. Ultimately it entirely depends on how developers approach them. If they add them, so it's Pay to Win, then a lot of players will stop caring about the multiplayer in its entirety. But CD Projekt Red president Adam Kicinski has an interesting take on their use.
"Well, we're never aggressive towards our fans!" he said. "We treat them fairly and we're friendly. So of course not--we won't be aggressive--but you can expect great things to be bought. The goal is to design monetization in a way that makes people happy to spend money. I'm not trying to be cynical or hide something; it's about creating a feeling of value." says Kicinski.
Normally, if they are purely for aesthetic's sake, such as cosmetics and costumes, then the common consensus is that it's perfectly acceptable because it doesn't change the balance of the multiplayer game. It seems CD Projekts Red stance is different when it comes to their single-player games, as they have said that no microtransactions will appear.
"Same as with our single-player games: we want gamers to be happy while spending money on our products," Kicinski said. "The same is true for microtransactions: you can expect them, of course, and [Cyberpunk 2077] is a great setting for selling things, but it won't be aggressive; it won't upset gamers but it'll make them happy--that's our goal at least."
It looks like all this talk about the multiplayer aspect of Cyberpunk that more information about it will hopefully be revealed soon. Especially, since the studio been talking about it's DLC, and with the quality of the DLC that was shown for the Witcher 3, I have no qualms that it'll be amazing.
