Since we started we tried to keep ourselves in the same place (for our own good, because of creepers and other monsters).
We started playing when the in-game time was already, since we had some communication issues between us, because of the microphones, so we had to hurry and find shelter. We spent a night in the middle of a little cave, made by ourselves, while mining some coal and cobble.
We crafted this map shortly after we got all the resources needed.
We didn't explore much of our surroundings, but I'm sure that on more than 3 quadrillion blocks that each Minecraft world has, it would take a loooooooong time.
And I'm not even kidding. Minecraft indeed has more than 3 quadrillion blocks - that would be like EIGHT TIMES EARTH's SIZE! Do you have any idea how big it is?
You could walk in a straight line for MORE THAN FIVE YEARS!
Don't believe me?
