Both shows are about survival game stories. The main character and it’s friends have different qualities in both shows. In Zero we have a Sherlock Holmes like super Brain and in Squid Game a person like you and me. The games are fun in both and ofc more creative in the Japanese version. Death Game shows and movies have their origin in Japan and they can do it best. If you had fun with the Korean dramas Liar Game or Squid Game then take it to the next level an dive into Japanese game shows. You won’t regret it!
