- **80+ structures** to discover
- **5 landmarks** as major goals

### **Progression:**

2. ✅ chunkSize undefined → Added to constructor
3. ✅ Double terrain rendering → Added safety check
4. ✅ Old terrain rendering → Skipped in biome mode
5. ✅ Chunks not visible → Debug borders added
6. ✅ Water not rendering → Connected RiverSystem/LakeSystem
7. ✅ Features on water → Skip feature placement on water tiles
8. ✅ Structure overlap → Minimum distance check
9. ✅ Roads on water → Water avoidance algorithm
10. ✅ Performance lag → Chunk-based optimization

## 🎯 **KEY LEARNINGS:**

### **Design Insights:**
1. **Initialization Order Matters:** BiomeSystem needed before terrain generation
2. **Chunk Size Critical:** 50x50 tiles = optimal balance
3. **Modular = Flexible:** Independent systems easier to debug/extend
4. **Transitions Natural:** Color blending creates realistic boundaries
5. **Performance = Priority:** 60 FPS non-negotiable

### **Development Process:**
1. **Plan First:** Clear session goals prevented scope creep
2. **Test Often:** Caught bugs early
3. **Document Everything:** Easy to resume after breaks
4. **Iterate Quickly:** Small sessions = faster progress
5. **Debug Visibly:** Red chunk borders helped tremendously
