It's my first world, but I can't believe the luck I had with it so far. It's amazingly rich in resources (haven't seen snow yet, but with the way this map has surprised me I wouldn't be surprised if I rounded a corner into a snow drift.), but I've found numerous dungeons with monster spawners, several pumpkins, lots of sugar cane, and of all the luck I actually built my first home structure literally on top of a massive underground cave system that spans across most of the map and has allowed me to discover other caverns in the areas nearby as well. You literally cannot go down there without myself or another player who knows it as a guide because you will get lost for days down there. It's insanely huge and definitely fun to explore. There's lots of lava down there and a few spawners.
At first when you spawn it would appear that there's nothing special about the place, few cactus', lots of sand, etc. but the more time I spent there I've discovered I actually had several forests, a few deserts complete with open lava right at the surface level, and mountains that were a joy to dive off from into the ocean. One mountain has a waterfall coming out of it naturally so I actually just put the finishing touches on a subway system to get to allow myself and supplies to get there quickly so I can begin constructing a massive castle just along side it.
But I digress...if anyone's curious you can enter the seed: eve
Several things: 1. If you want to explore that hellmouth of a cavern I accidently built my first home on, walk up from the spawn area, towards the ocean near a grassy overlook where you'll find lava pouring out of the cliff side naturally into the ocean. I chose the spot because it had lava, water, and other resources naturally close by, never realizing the amount of resources buried underneath there and other locations. 2. Most of the treasures in this seed are quickly found simply digging down a bit.3. If you don't want to dig, follow the shore lines to a forest nearby, there will be huge holes in various locations leading to other massive caverns, and one nearby cave with a spawner in it easily seen at night from the shore.
There is no mystery...only truth.
