Ive hit 'max gear' on my new guy, on seed Q2W3E4R50. Ive found some cool stuff.. 2 boat wrecks on top of each other, and now I was exploring a mountain for a cave and .. trudging thru the snow, I reach the top and look down... and see a pristine valley of plains and dark forest, rather small, surrounded by a giant mountain range. I am building there now..

Current Seed: WetFart
Interesting notes:
-You start on a continent that easily takes up 10% of the possible land mass on the map.
-There is an island that you could find that has a tiny meadows biome situated on the coast that leads to a tiny opening between two mountains that can effectively be a mountain pass for any would be kingdom builder.

Iteresting idea. I just explore the world with seed "uZReVrT9xW" . On the spawning island is very few burial crypts with very few surtling cores inside. On the initial isladn i started with 7 surtling cores - it is not enough for the bronze smelting (i have made the coal, then smash the furnace and made the tin, copper and bronze ingots, then smashed again ...). Also there is very few troll caves and if - they are empty ...
