I have just learned about it but it sounds pretty interesting. It is a game where everything is worth real money. Not sure how it works just yet but it has caught my attention.

Tried it out, maybe 9 years ago now. It's been around in some form for much longer than that. Actually surprised it still exists.
Was broke at the time, and so a game that effectively demanded external capital or to play it as a job wasn't desirable. I remember the gameplay was viable but unnoteworthy, though I'm way out of date for that now.
There's clearly a market for what it offers since it still exists. Whether it's a good game, that's personal preference. Being a play to earn game from before the term existed might be the biggest boon it has.
Hope that's useful.
