I've spent quite some time on my survival world and I thought it would be a good idea to upload it here. :D
This world was a huge ocean world as seen in this video(http://www.youtube.com/watch?v=u0TPcD2SSs8). I had to find the main island as I was running out of sand so, I traveled roughly 20 minutes by boat in a certain direction. Hence, the huge world size. The villagers from the iron farm were taken from the main island.
My world consists of a monster spawner, enderman farm(not efficient), iron farm(standard type x4), wither skeleton farm(not efficient), automatic cactus farm, huge wheat farm, AFK fish farm, spider spawner, snow farm and an automatic chicken farm.
I've 10 beacons, 40+ name tags, 35 double chests full of string, a double chest full of iron blocks, a stack(and a little more) of diamond blocks from the 1.5 duplication glitch, two circular islands with a radius of 50 blocks(perfect for beacons) with the home island in the spawn chunks.
I intend to build the Iron Titan on my home island while having my central storage area, automatic brewer and super smelter on the 2nd island. I also intend to build a gold farm somewhere around my spider spawner so I can obtain lots of gold from AFK-ing at my fish farm. I also wish to build a witch farm and a AFK sheep farm sometime in the future. Other than that, I would definitely like to light up all the caves within a 250 circular radius of the main beacon on my home island.
Note: The ONLY times I used creative mod were to place the LONG line of glass above my minecart tracks in the Nether, which leads to the main island, in order to prevent zombie pigmen from spawning and to bring in command blocks for teleportation purposes which can be found in my Old Mines and to and from my Enderman farm.
