Requirements: Python 3.12+, Nim 2.2.6+ (via nimby), OpenGL

```bash

# 1. Install Nim with nimby

curl -L https://github.com/treeform/nimby/releases/download/0.1.11/nimby-$(uname -s)-$(uname -m) -o ./nimby

chmod +x ./nimby && ./nimby use 2.2.6 && ./nimby sync -g nimby.lock

# 2. Install Python package

pip install -e .

```

```bash

# Play interactively (builds Nim library if needed)

tribal-village play

# Run with random actions (text mode)

tribal-village play --render ansi --random-actions --steps 100

# Train with CoGames/PufferLib

pip install -e .[cogames]

tribal-village train --steps 1000000 --parallel-envs 8 --num-workers 4

```

Controls: Arrow keys/WASD (move), U (use/craft), Space (pause/step), scroll (zoom), Ctrl+1-9 (control groups)

• Victory conditions: Conquest, Wonder, Relic, King of the Hill, Regicide
• Tech trees: Blacksmith upgrades, University research, Castle unique techs per civilization
• Production system: Batch training, production queues, per-unit training times, rally points
• Military commands: Attack-move, patrol, unit stances, control groups
• Economy: AoE2-style market trading, Trade Cog dock-to-dock gold generation, biome resource bonuses
• Unit mechanics: Garrisoning, Trebuchet pack/unpack, Monk conversion, Scout exploration, unit upgrades
• AI system: Role-based agents (Gatherer/Builder/Fighter) with inter-role coordination, shared threat maps, adaptive difficulty
• Terrain: Biome zones, elevation with cliffs/ramps, mud and shallow water, terrain movement speed modifiers

```python

from tribal_village_env import TribalVillageEnv

env = TribalVillageEnv(config={

'max_steps': 10000,

'render_mode': 'rgb_array', # or 'ansi'

})

obs, info = env.reset()

obs, reward, terminated, truncated, info = env.step(actions)
