## What it is
Permafrost Engine is an OpenGL 3.3 real-time strategy game engine written in C, inspired by classic RTS games. It provides rendering, skeletal animation, terrain, pathfinding, and a Python 2.7 scripting interface with an embedded console.

## Use cases
- build a real-time strategy game in C
- engine with flow field pathfinding for large unit counts
- OpenGL 3.3 rendering engine with skeletal animation
- script game logic in Python
- RTS-style camera and formation-based unit movement
- render huge tile-based maps efficiently

## When to choose
- you want to build an RTS game in the style of classics like Age of Empires
- you need hierarchical flow field pathfinding and collision avoidance for many units
- you prefer a C codebase with Python scripting
- you want a built-in map/scene editor and UI framework

## When to avoid
- you need a general-purpose engine for genres other than RTS
- you want modern high-level tooling like Unity or Godot
- you require Python 3 scripting rather than Python 2.7
- you need cross-platform console or mobile targets
