I always assumed the reason they repeated that line and only implied it was for headaches with the animation is because they knew it wouldn’t work and wanted to avoid being called out for false advertising. Honestly if I was ever told it worked I would be absolutely astounded.
The long dark.
Assuming the game mechanics are still in place? I’ll be fine. Maybe I’ll even live a few years on the Great Bear island.
However, if I am in that scenario with real world mechanics? I’m Fucking dead, so hard, so fast. Then again I guess the wildlife would be less aggressive and maybe people would actually be around. Still probably dead, though.
