Fauna Generation Plan

For fauna, I want the system to handle animals in broad ecological groups: predators, herbivores, and animals that fall somewhere in between.
1. Basic Animal Types

First, we should define basic animal types that can exist in many different environments. These are not specific species, but general animal categories.

For example:

    Rodents
        Desert rodents in desert regions
        Swamp rodents in swamp regions
        Forest rodents in forest regions

The same approach should be used for other common animal groups that can appear across many biomes.
2. Animal Classification

For regional animals, we should describe them more by broad biological classification and size rather than by exact genus or species.

The classification should use something like:

    Class
    Order
    Family
    Size category

Example:
text

Animal: Cat-like predator
Class: Mammal
Order: Carnivora
Family: Felidae
Size: Small

A tiger-like animal would use the same family but have a larger size:
text

Animal: Tiger-like predator
Class: Mammal
Order: Carnivora
Family: Felidae
Size: Big

Size categories could be:

    Tiny
    Small
    Medium
    Big
    Huge

If more biological information is needed, please ask me. You can also look up general classification information if needed.
3. Cell Population System

Each map cell should be populated using a slot and point system.

For example:

    Each cell has 10 fauna slots
    Each cell has 20 fauna points

Every animal takes up a certain number of points depending on its size:
Size	Point Cost
Tiny	1
Small	2
Medium	3
Big	4
Huge	5

Animals are added to the cell until either:

    All slots are filled, or
    All points are used

Once one of these limits is reached, the system stops adding animals to that cell.
4. Regional Distribution

To create a more homogeneous and natural distribution, the system should check neighboring cells when populating fauna.

The rules could be:

    If neighboring cells have the same climate, there is a high probability that the same or similar animals appear there.
    If neighboring cells have a different climate, it is more likely animals should be generated instead.
    Similar biomes should share more fauna.
    Very different biomes should have more distinct fauna.

This should help avoid every cell feeling completely random while still allowing variety between different regions.
5. Overall Goal

The goal is to create a fauna system that feels natural, biome-based, and regionally consistent, without needing to define every animal as an exact real-world species. Animals should be generated from broad biological groups, ecological roles, and size categories.
