Obviously, he's not going to murder a whole bunch of people for it, but he's spent a whole heap of cash in making it happen and on recreating all of the games from the show.
So, he claimed that more than $1.5 million in prizes were to be given away and that he wanted to get the full complement of 456 contestants onto the show - just like the real thing - and it seems as if he managed to pull it off.
As everyone who has seen the show will know, he has mocked up real-life versions of the games such as Red Light, Green Light; the Tug of War, the marbles game, the glass hopping challenge, the honeycomb game and the final showdown - the eponymous Squid Game itself.
However, the YouTuber mixed things up a bit for that final challenge.
Instead of playing the iconic South Korean children's game called Squid Game, he opted to do musical chairs because he knew none of the contestants would know the rules.
To be fair, even if it was explained, you wouldn't have the different tactics involved. Musical chairs seems far easier and relevant to Western audiences.
People absolutely loved how much effort he put into this recreation.
One viewer wrote: "Jimmy this is incredible. At this point you should take the next logical step and establish a movie/ tv production company- you've pretty much already created one from scratch. I would love to see how you could shake up that industry."
Another added: "As a Korean this is impressive."
A third said: "I was one of the people who helped make this set. Definitely the hardest I've worked in a while but also the most fun I had in a while. Working these long hours for weeks definitely paid off. Thank you for this unforgettable experience!"
The YouTuber - who is actually called Jimmy Donaldson - has put up huge sums for those who win. However, fail at one of the games and you're out.
It's better than the outcome of the TV show, but it'd still be disappointing to miss out on a life-changing chunk of dough.
Writing on his social media earlier this week, MrBeast wrote: "Our Squid Game with 456 random people competing in exact recreations of every game will be uploaded on Wednesday."
Well, here we are... it's Wednesday and we've finally got the full video!
He actually came in for a bit of criticism when he first announced his plans, with some questioning the amounts of money involved, and others suggesting that - given the true nature of the show - it's in slightly poor taste to recreate it in reality.
One person said: "The whole thing was about the people killing each other to get out of debt as entertainment for the wealthy.
"Glad that went over your head and you, as a wealthy person, are recreating it as entertainment."
Another said: "Y'all take things too far. juts enjoy the show like normal people and move on."
However, others are just looking forward to the fun, with one tweeting: "This is amazing! Can't wait to see it,"
Another said: "This looks insane!"
