Niche
TS engine for AI-driven worlds. The differentiation is not engine breadth (Babylon, Excalibur, Phaser, Kaboom all do that well already) but:
  • Cross-session NPC memory via NarrativeMemory (v1.3.5)
  • Asymmetric relationships via RelationshipGraph + EmotionState
  • Deterministic replay via mulberry32 + clock seams
