Minecraft Pokecommunity Ultra Hardcore would be very interesting.
For those of you who are unaware of the concept, everyone spawns in a random place in a map with a border. The game is locked on to hardcore mode (meaning if you die, you're out), and health regeneration is disabled. The only way to regenerate health is crafting a golden apple, which now requires 8 ingots as opposed to nuggets, or tackling the nether and getting some health potions. You can also craft a golden head in the same manner as a golden apple using a player's head, which drops when a player dies, and gives double the health of a golden apple.
The winner of the game is the person who outlasts all the other players, which will require going out and fighting others, killing them for not only their equipment, be it gold or diamond, but also to move one step closer to winning the game.
I have my own server with all the plugins so hosting it isn't a problem at all.
I'll post some videos of examples if anyone is still confused but I'd have to log into my otheraccount (Fireworks) which I don't feel like doing atm so I'll get to it later.
