So Keanu Reeves in trailers/in the game as a character and a secondary lore character who resembled the main character, on the "reveal the game" stage, using Billie Eilish music in trailers, a famous musician married to Elon Musk as a voice actor for the biggest celebrity in the game, and to boot you can also find Hideo Kojima (with a different name, but with the same kind of background) in the game, are not celebrities enough for you?
They had around 8 million pre-orders in total, you can bet that it wasn't just few hundred peeps on sony console, maybe if you only count ps5 only users, considering one shop blocked 20 million bots from buying a new stock of ps5 consoles.
Sony stopped them making refunds at first, thus it was pulled from the digital store, and the refunding was activated again. Sony even changed their policy on refunding pre-orders, at first you could refund at any time, like get the rewards or demos from it, and then refund it.
(If you have paid for pre-ordered content on PlayStation Store but have changed your mind about the purchase — you can request a refund. PlayStation Store refunds can be issued for pre-ordered content, as long as the request is made before the release date, or within 14 days of purchase, and the content has not started to download or stream.
Please note, if you have started to download the main part of the order, you will not be able to request a refund. Please be aware that downloads will happen automatically if Automatic Downloads are enabled in your system settings."
