I think it's the same reason so many people want to become streamers, or actors,

Live service is a winner-take-all market, where if you hit it big you get SUPER big, and because the biggest names dominate the landscape you see them more and it's easy to forget that for every Fortnite there are hundreds of The Cycle: Frontier.

But when you're starting out it's easy to convince yourself you're going to be the next Fortnite, so you rush down that road rather than more reliable-but-boring ones like "I'm going to make the next Baba is You".
