I've been thinking about this for a while, and here's my idea.
How far can you go in Minecraft? I'm talking chests and chests of diamonds, a giant castle, a huge amount of food...not in SMP, without cheating...in survival single player.
My challenge is to do all of this:
1: 5 Stacks of Diamonds (minimum)
2: 25 Stacks of Iron ingots (minimum)
3: 10 Stacks of Gold ingots (minimum)
4: A wheat farm that produces 6 stacks of bread PER CYCLE.
5: A sugar cane farm that produces 1 stack of sugar cane PER CYCLE.
6: A melon farm that produces (approximately) 3 stacks of melon slices PER CYCLE.
7: A pig, cow and sheep farm that produces (approximately) 3 stacks of pork, steak and wool (respectively) PER CYCLE.
8: Go to the Nether.
9: Defeat the Enderdragon.
10: Have a house that is 50x50x50x50 blocks in size.
Any player who completes the above 10 challenges (with proof) will have their name on the follow list as one of the Champions of Minecraft. There can be 15 Champions of Minecraft.
Any player who completes the above 10 challenges (with proof) in Hardcore mode will have their name below as the God of Minecraft. There will be only one God of Minecraft. (if any)
