In 1.5 I spawned in the middle of an ocean near a cluster of very small islands. The one I call "Driftwood Island" had a single tree and became my home. My objective has been to live off of ONLY the resources I can gather on my cluster of islands and the caves beneath. There are certain resources I will never have, but it has added an element of resourcefulness to the game that I really enjoy. When 1.7 came out the new fishing mechanics changed the game for me because I could get leather and therefore enchanting. I have also done some exploring in search of other islands with exotic resources, but I have not made landfall on any large land mass.
