I read a comment that summed up this cast that said "We have people wanting to lose on purpose out of sympathy, people who don't know what the fuck they want to do in this game and end up voting for themselves, people who want to intentionally help a player because he's good looking." Watch and see exactly why the majority did not return, even in season 3.

I'll add on that it feels miraculous this got more seasons when they literally casted two legendary Genius participants to mock their cast almost every episode for making questionable plays in games that were subpar compared to the concept that promised betrayals, revenge, and "anything goes" behavior to win.

On the bright side, we got an iconic performance from Jimin and better changes in the following seasons.
