Both Variety Shows have a sport and game element to it. There has been many idols on RunningMan as guests. Both are entertaining to watch, though RunningMan has more comedy in it.
Pretty much similar to few of the episodes in the OG Running Man episode, give it a try and you surely understand why. Both intense and brilliant idea of a show.
You will laugh a lot watching both and you will feally love the cast.
This are the two best korean variety shows that I know, I am pretty sure that if you liie one you will like the other.
