I think NPC's would make it a lot more like Hand Sim, but NPC's (Physics based especially) are hard to implement.
Viewing post in Physics VR: Survival comments
Physics-based, fully articulated NPCs are certainly difficult, but really cool. I’ve seen close to no implementations in VR with a degree robusticity I’m satisfied with. It seems to me that they’re the next step for in-depth VR physics interactions, and in that vein they’ll be the main focus of my next ~2 releases. Traditional, bespoke AIs haven’t sufficed, so I’ve been lost in the sauce of neural networks
