Multiplayer map with lots of stuff to do

This is just a complex of cool things I made, including floating structures, mob arenas, PvP arenas, and cool redstone machines. Please leave a comment saying which of the things you like the most, so I can know what to spend more time on making even better. Now includes HungerGames, Last team or man standing PvP, strangely survivable 50 block drop in survival mode, and a random elevator. Also, these each have mostly functional plugins made entirely out of vanilla redstone.
