The ranked members will have to think more in a macro sense as much of the trial and error plans we have been using won't work on a faster time scale. The unintended consequence of this is that it will bring the next crisis forward all that much faster without much time to develop anything else. It also reduces our reaction to when a crisis does pop up. Say if the slavers try to escape again it will be a whole day before we could react to it. I do think there is also a lot to gain from a faster time frame. Projects will go much quicker. If done right instead of spending three turns opening the doors in the basement it could be done in one turn. Similarly we could also open the mine faster and have the crafter and forge produce more goods for us.
Overall I have mixed feelings with this. I am all for trying the faster time scale but we should realize it won't solve all our problems such as the unemployment issue. Only spending real time and attention on this will solve it.
