The Zone of Luminescence

Should I add random events? They'd be like Plauge, instant halved population, or Famine, instant halved food. There would also be Large Harvests, an instant +50 food.

Bad events would be on a 1 in 1000 chance. Good events would be 1 in 2000. I'd use random.org to get fully random numbers, so there would be NO bias here, but hey.

I'd like other people's opinions.
