Thanks. But, I'm not a bit confused. The probability of any event occurring depends on its cost. So, do you pick one at random (which we don't know) and then calculate the % chance of success each turn, and the attacker can't know the % success because s/he doesn't know the cost? And, can the event only occur after you've spent the total cost, or do you calculate the % success each turn, with more expensive projects just having lower % chance?
Thanks! DB
