The new feature in Minecraft Beta 1.3 is the map generator which you can use your own seed combinations, I have been trying different combinations using some that I found over the internet and I'm sharing my favourites. Most of them are overall worlds and how they look and one is at a specific place. Ok, so here they are:
Number 1:This is probably my favourite for a few reasons, overall I like worlds that has massive mountains and a fair bunch of trees, this world not only has those but has water and lava springs from the cliff face.
Seed: ö
Location: The whole world has a lot of trees and mountains but the picture below's coordinates are: x=-12, y=67, z=-107
Picture/s:Number 2:This world is again full of mountains and also has very large overhangs and a few small floating blocks. Most of the land is grassland but there are a few large patches of beaches and sand.
Seed: 1987
Location: The pictures coordinates are: x=27, y=67, z=-2
Picture/s:Number 3:A normal kind of world but there is a slightly strange thing that happends when you dig an area of gravel... Go to the coordinates and dig the 1x2 area of 1 block deep gravel (as seen in first picture) once dug the gravel should now look like the second picture. A hole right to the bottom of the world, wait for the water to flow down to make it safer to go down. There are a few other caves that open up once you do it.
Seed: 404
Location: x=-27, y=65, z=23
Picture/s:So those are my main favourites, post any of yours that you have found and liked
