I was trying to make a good world to post on my server, and was typing in random junk for the seeds, and this is what I got. A hardcore survival island. No trees anywhere nearby. Large caves all around. So I decided to post it, and add some rules. Here they are
#1 NO CHEATING
#2 See #1
#3 See #1
#4 See #1
#5 See #1
#6 Play on at least normal

Here are some objectives I made up too.
#1 Find a tree
#2 Make a TNT block
#3 Kill an enderman
#4 Find diamonds
#5 Make a bow
#6 (optional) Find and kill a spider jocky
#7 Find the stronghold
#8 Kill the enderdragon
#9 Build a large house
#10 Post how well you did
#11 Diamond this

Thanks!
