I don't think it needs a season 2 either but we will get anyways. I don't want to see gi hun as some sort a hero who wants to stop this game from happening. I prefer Alice in Borderland than Squid Game. Unlike Alice in borderland, gihun and others went to the game voluntarily .I could easily picture Arisu as some sort of hero as they were forced into game and had no choice but to survive. But I cant picture Gihun as a victim I see him as a winner of this game so I kinda cant see him going behind the mastermind to get justice for the life's lost.
Also Aib got me thinking " What will happen next?" "What is the next game?" " How will they solve it?" . As for SG , the games didn't interest me much.
Bringing back character after death is not likely I am guessing.
