If I get this right
So the reason why Bada and Doha become a "player" is bc they each have a tape (save file) that lets them play the game, right?
And that Pi something used to be a player as well but bc his tape was ejected now he's just an NPC?
Does that mean that if someone ejected Bada or Doha's tape they would turn to be an NPC too? Is this bad? Would getting more players actually be bad?
Someone help me
