Multiverses

Multiverses are separate planes of reality, with little to no possible interaction with each other.

The "Everything is Connected Multiverse"
The Multiverse where most Talking Games take place is the Everything is Connected Multiverse. This is the second largest known Multiverse, with many Universes inside of it.

The Severed Multiverse
This Multiverse doesn't have many Dimensions, and was created to serve as an "Alternate Timeline" for Talking Games that didn't want interference from other Dimensions.

The Void
Home to Albert and Trebla, The Void is an barren Multiverse filled with nothing but a Battlefield.

Universes
Universes, or "Worlds", unlike Multiverses, can be crossed. The act of crossing Universes is called a Dimensional Jump, and to do so one would have to be located at a Dimensional Hub. While Universes within the same Multiverse can interact with each other, Dimensions from different Universes can not.

Dimensional Hubs
Dimensional Hubs, or "World Portals" are structures with Dimensional Gateways to direct Heroes (or Villains) to other Worlds. While some Dimensional Hubs contain multiple portals, some only contain one. Some notable Dimensional Hubs are:
 * A Castle-like Hub within a Zelda Dimension, where the Battle of the Heroes took place
 * A Presentation Hub that connects the My Little Pony Dimension, and a Skyward Sword Dimension

Universal Hubs
Universal Hubs are alike to Dimensional Hubs, except instead of traversing Dimensions, they connect entire Universes. There is currently only one known Universal Hub, and that is The Void.

The One True Universe
The Multiverse that anyone reading this Wiki page right now is in is The One True Universe (or Earth-1218). The One True Universe is the only Universe that actually "exists" and in which all other Universes are just ideas. Albert is constantly trying to inform everyone of the True Nature of the Universe, which is that none of the Universes except the One True Universe exist at all, and that they actually are just "toys being controlled by hands".

Corrupted Universe
A Corrupted Universe is a Universe where everyone within knows that it is not real, therefore granting everyone extreme reality bending abilities, such as Destroying the World, Re-creating the World, Insta-Killing, Reviving, and effectively turning everyone into an all-powerful being. A Corrupted Universe will likely cause chaos, as everyone will have a comeback to anything, because there literally are not rules. The only treatment for a Corrupted Universe is a complete world reset, back to the point before the godmoder came in.

Trivia

 * A great example of a corrupted universe would be the Destroy the Godmodder universe, a game on the Minecraft Forum.
 * Knowledge of other Multiverses is scarce within any universe, only known by Albert, Trebla, and one other.
