When a player walks in to an arena they can’t leave until another player died in that arena, no commands to join it, you just walking in, the prize is a chest that cannot be unlocked until the other player is killed. For example if you had 5 players you would need to kill all four to open the chest and because there are no command to join if you logoff you will still be playing when you login to quit you must use the command /Idone
Your idea of this game seams like it doesn't rely on any plugin. Except for the ending which I bet another plugin can do. Like warp commands.
