Thank you all for the feedback. With the majority learning towards staying at a 48 hour schedule, and with nobody speaking strongly in favour of an increase, I will now not be increasing the hosting to 60 hours as advertised/stated on the games status page.
My current intentions now are to think about moving to a 72 hour schedule at turn 72. So I will bring up the subject again near to that time, when I will again ask you all for your thoughts to see what you all think
Thanks again everyone for all the replies.
