Yeah, I never said it had to be identical to the books. but It ruins the style of the "Hunger games" as stated before, it won't work IMO and if this gets added, I will actually think about quitting MCSG and many other people will.. It's just stupid and unrealistic.
It doesn't really change much though, it just enhances it. All it would do is force people to fight in the last 10 minutes, isn't that what deathmatch already does? By giving away the location of other players 10 minutes before deathmatch already starts, it kinda forces them out of hiding and stops them from running. This already happens at deathmatch due to the fact that if you run, lightning strikes which forces you to fight.
Giving players a compass 10 minutes before deathmatch starts and creating a deathmatch which doesn't have any lightning strikes until after 10 minutes has passed would create exactly the same effect, forcing people to fight and getting rid of those who hide.
It could work and I truly doubt that a large number of people will quit if it's implemented. The idea is pretty good, although it could be developed more. And unrealistic you say? It's minecraft, it's not supposed to be.
