Random World Generation

 is the name given to the generation of a game using the random gen map in 7 Days to Die.

The random gen map is a randomly generated world created using your game name as the seed. Players may also perform Custom Seed World Generation using the "Advanced Generation" option.

When a player opts to play using, the name they give the game decides how the terrain will be generated and which Points of Interest will be placed where. For example, a game using the name "Survive PvP" will be completely different from a game using the name "Survival PvP", both of which will be different from a game using the name "7 Days to Die".

Cell Rules
The terrain in a map is broken up into cells whose size is specified in. Below is a list of cell rules including the probability that each cell rule will be implemented in any given cell.
 * Cell Rule - Default - 100% chance

Hub and Wilderness Rules
Each cell rule also comes with a hub rule determining what type of settlement can spawn in the cell, and a wilderness rule determining what can spawn in the wilderness of a cell. As of Alpha 15.2 High Density and Low Density cell rules have the exact same hub rules. Here is a list of hub rules and wilderness rules for each cell rule.
 * Cell Rule - Default
 * Hub Rule - Town Small - 27.27% chance
 * Hub Rule - Town Large - 27.27% chance
 * Hub Rule - City Small - 9.09% chance
 * Hub Rule - City Large - 9.09% chance
 * Hub Rule - Rural - 27.27% chance
 * Wilderness Rule - Wilderness Default - 100% chance

Prefab Rules
Every hub rule and wilderness rule contains a prefab rule to determine what Prefabs can be spawned in that hub/wilderness.
 * Hub Rule - Town Small
 * Prefab Rule - Default - 100% chance
 * Hub Rule - Town Large
 * Prefab Rule - Default - 100% chance
 * Hub Rule - City Small
 * Prefab Rule - Default - 100% chance
 * Hub Rule - City Large
 * Prefab Rule - Default - 100% chance
 * Hub Rule - Rural Small
 * Prefab Rule - Default - 100% chance
 * Hub Rule - Rural Large
 * Prefab Rule - Default - 100% chance
 * Wilderness Rule - Wilderness Default
 * Prefab Rule - Wilderness Group - 100% chance

Prefab rules can override other prefab rules, or they can contain a prefab. Each rule or prefab inside of a prefab rule has a probability that it will spawn in the cell.
