For the Hunger Games, there should be a sudden death when the games last forever with only ~3 players in there. They spend most of the time trying to find each other. When it has been a few minutes, just force TP the last few players to the arena's spawn. I don't know if this will be a good idea, but with 300 players online at most, one game could last 30 minutes.
In one game it was me vs mattybillo1 he was stuck down a hole and I could not get to him. We refused to back down and so the game ended while I went afk. So an idea like this would be great! +1
Got in a game that lasted 2 hours last night, :/ Really wished we had the tp to spawn features near the end of the match. :| Me and the final guy just ran in circles chasing each others lightning, lol.
