Minecraft wiki entry for Speedrun, associated text: Random seed: The player begins a new world using a random seed. However, it is not against the rules to start a new world, look around for a village or other useful features and restart with another new, random world if necessary. Speedrunning would be trying to beat Minecraft as fast as possible. However, there is something called long worldplay. Long worldplay would be like trying to create a civilization, and keeping it alive. There are plenty of different blocks and an infinite amount of combinations to the builds, block color palettes, and different contrasts for the blocks. This might take years, or just days to get this going. Speedrunning does take a little time, and the fastest record for a minecraft speedrun is under ten minutes.
