Overworld

The Overworld is one of the three vanilla (natural) dimensions in Minecraft, and by far one of the most prominent. You spawn in the Overworld, and is one of the most active and chaotic places in the 2b2t world.

History
In December of 2010, when 2b2t started, the game was in Beta 1.2/1.3. Minecraft's Terrain generation changes for every version you play in. For example, loading a chunk in Beta 1.7 will not be the same with a neighboring chunk loaded in 1.8, and vise-versa. All chunks loaded during this time were dubbed "Beta" or "Alpha" Chunks, a reference to older terrain generation. As the game progressed, the Overworld saw drastic changes such as:
 * A higher build limit
 * Biome changes (ex: Snowing in a Desert)
 * Chunk "Glitches" (chunks neighboring each other that have different generation, or deformed/reset chunks due to World Corruption)

While these changes are visible in other dimensions, it is thought they're more prominent in the Overworld. The Overworld was also the first ever dimension to spawn in 2b2t as players spawn there and there was no End in 2010.

Resources
Resources are prominent in the Overworld, specifically Wood, Ores/Minerals, Stone, and many more materials usually unobtainable in contrasting dimensions.

World Border & Farlands
The Overworld World Border's history is spotted. At first, after the expansion of the -X Axis Highway, it was thought that chunks from beta were generated from a backdoor as there were prominent and visible, meaning a suspected player could've reached the World Border at this time (even thought it didn't exist until 1.7/1.8). It was later confirmed to be generated by iTristan and pyrobyte in an unrelated backdoor. It was officially reached in 2017 by the Nether Highway Group via extending the +X Axis Highway.

The Farlands were a phenomenon deleted in Beta 1.8 by Mojang. They spawn at 12 Million overworld and it is thought that nobody visited them except for the original policemike55. Fit released a video claiming a $2,000 for anyone who could prove they found them.

Transportation
Transportation in the Overworld is looked down upon. Roads are poorly maintained in comparison to their nether counterparts, as the nether is a much preferred way to travel, being that 1 block in the nether is ~8 in the Overworld.

Famous "highways" or roads in the Overworld include the 8 main highways stretching from Spawn, the Southern Canal, and the Old Spawn Road.
