I don't know enough about Fortnite, but at some point if the metaverse wants to escape the "it's just a video game" trope, it's going to have to be... More than a video game, I guess ?

Can epic do that ?

Facebook a least "invented" a form a "passing time" (I'm being generous not to call it wasting time) that doubled as an advertising and marketing platform. And even that only took aff with the advent of smartphones, which enabled "using Facebook / twitter on the go" (and, more accurately, "on the loo").

When there's a VR helmet attached in every toilet, though... I'll sell hemoroid creams :)
