Found 2 pretty cool seeds; asdfjkl; and diamondzdiamondzyay.
the first seed is cool, start off in a snow biome, there is a lot of flat land, good for building a castle or something, and the diamondz seed is like the bahamas or something, tons of islands, there was alot of reed (sugar cane) and clay near the spawn point.
i just wonder if their are any seeds that we know of that has more diamonds then normal
I got the serial number from the crashed vertibird in Fallout: New Vegas and used it as a seed. It creates a beautiful mountain range directly in front of you when you spawn. (may take a few seconds to generate) There is also a very nice, flat valley within. Great for building!
Caution: There are plenty monster-filled caves in the valley.
Note: Name the word the same as the seed, as I heard the name sometimes affects the spawn point.
