1. Arena would be set up pretty much the same as ffa, the only changes to this style would be.

2. Set a cornucopia (which will add chests in this area with basic items defined in config, at the
start of the game, if possible)

3. Can build/destroy within the arena

4. Ability to sponsor (if your unfamiliar with the HG then this would mean people who arent playing can
sponsor a player by teleporting to them during the games and giving them some items, prob easiest to
use classes for this to set the items which they can give.)

5. Keeps track of who has died/still in the game and provide a list of this with a command.
(possibly show a msg of who has died and how many are left)

6. Each player teleports to a different starting point.
(using ffa i found players were being tp'ed to the same point even tho multiple were set)

7. I think thats all, i will edit if i think of more.

EDIT

*a few personal requests to make it more like the book/film*

8. A message at the start of the game saying "MAY THE ODDS BE FOREVER IN YOUR FAVOUR"

9. A message when joining saying "welcome to the 1st/2nd/3rd(and so on) annual hunger games"

10. My arena is surrounded with bedrock so they cant leave the area.
Currently your plugin teleports them back to the starting point which i think would be a problem considering
the players must hunt each other down. They will just wait at the start for someone to be teleported back
there. Perhaps if you could make it tp them back a few spaces into the arena or just stop them leaving
entirely by protecting just the surrounding walls.
