ROckWrok
The population’s got to ROckWrok.
It’s the stone age, at least that’s effectively what you’ve got to mine, stone, in order to make what you need you’ll also need some deliveries from the sea.
The chastened, the chasing, amazing the neighbours.
Anyway, about 40 minutes should do it and don’t destoy any tracks (so that means crashes are bad too) and don’t deliver to the wrong place.
