My fear is over what it will take with it when it goes.
A lot of companies are so reliant on their current cash cow that... who knows how badly they would get hit to be honest. Like, does Epic have anything very successful going on besides Fortnite? The Epic Store was a clear attempt at creating a safety net in the event Fortnite dried out but that store hasn't caught on as much as it needed to. Well they have Unreal and the whole stack of game development related platforms, but it would still be a big hit.
But who knows, what comes next may be compatible with the video game industry in a way that it can profit from it.
If I had to guess, what comes next is either an insane evolution of Roblox-esque metaverse user community spaces (fortnite is already heading there after all) or a revolution of short form media that allows user generation, consumption and participation in a manner that we can't currently fathom.
So either "Roblox 3.0" or "TikTok 2.0 meets those-twitch-AI-shows-that-went-viral-for-a-minute 2.0".
But I'm probably waaayyyyy off the mark. But whatever it is, it will be setup around the idea that you are only cool if you have X and X costs stupid amounts of money.
