Old game NPCs followed scripts — "if player walks within 5 feet, say line A; if player attacks, run." That's it. They couldn't really react. The Skyrim guard who said "I used to be an adventurer like you, then I took an arrow to the knee" was the same line you heard 50 times for a reason.
What's actually new
LLM-powered dialogue: NPCs that can chat about anything (Inworld, Convai)
Smarter enemy pathfinding: bots that flank you instead of running into walls
Generated quests: missions that adapt to your character
Voice models that voice-act in real time
Why studios are slow to ship it

Reality so far
Infinite dialogue!
Sometimes says weird stuff that breaks the game's tone
Smarter quests!
Hard to make sure they're fun every time
Living world!
Costs money in cloud bills per player per minute
Try it: chat with an AI NPC
Try the AI NPC demo at AI Town (a-town.replit.app) or Convai's free demos. Chat with an NPC for 5 minutes. Notice when it feels alive and when it slips up. Then think about what your favorite game would feel like with NPCs like that.
