Dimension
Dimensions operate as completely different worlds, and may be linked by creating portals. As of 1.7.7.0, Better Than Adventure contains two normal dimensions, and intends to make use of three in the future.
The Overworld
The Overworld is the dimension the player starts in. With its wealth of natural resources and mostly hospitable biomes, this world is more than ideal for one to reside in. The overworld has a trove of new features absent in it's vanilla counterpart, such as seasons, new

weather conditions, and a few new biomes.
Unlike other dimensions, the player may choose different world types for a unique experience.
The Nether
An uninhabitable infernal world, the nether is a lifeless, dangerous place to be. Only featuring the Zombie Pigmen and Ghasts in its current iteration, this barren world of caves does not have too much in it, aside from its deposits of Nether Coal, Glowstone, and oceans of deadly lava. The nether is at a 1/8th scale with the overworld, and is very useful as a method of fast-travel.

In order to reach the nether, you must build a hollow rectangle of obsidian with the corners filled in, and use a fire striker to activate it.
In the future, there will be a new area directly underneath the nether: the warrens. This area will be comprised of a labyrinthine network of tunnels. Due to an incredibly hard layer between the warrens and the standard nether, it is ideal to locate a Quarry, an upcoming structure that has a hole connecting to the warrens.
Another area above the Nether known as the “Oldworld” has been discussed, but it’s implementation is not yet confirmed.

Paradise
Paradise is a planned dimension for a future version, there is a very incomplete placeholder in the game currently. In its current iteration it is a world using the floating island generation, with no mobs naturally spawning in it.
This world has two seasons: “Gold” and “Silver”. These alternate every 28 days.

The dimension will likely have an inverted scaling compared to the Nether.

To visit this dimension in its current iteration, make a portal out of glowstone, and light the inside with bedrock.

Future plans for this dimension are vague, although this world will likely focus on exploration and contain structures and biomes
Trivia
- The Nether is not Hell, but it is "Hell-Like".
- Unlike the Nether present in Vanilla, the Nether will not feature anything alive, nor will it have any plantlife or foilage.
- The Oldworld concept originated as a fanmade suggestion on the discord server.
- Paradise was going to contain Mithril ore, a green metal which would provide a Looting-like effect with the tools. This has been scrapped, and will not make it into the final game.
