That's a sure case of "Who cares if it's realistic or not?". There have been endless discussions of how the fatigue system is unrealistic, as are all the different mods to change it.

This is the first sub sim to actually have crew management. If you want to manage them by removing fatigue altogether, you have nothing to apologize for. :rock:

Well i'm all into the realism, but that is one aspect I just don't want to worry about. I respect that they put it in there for those that do like it, but I have no interest in taking care of them to that level of detail. Maybe one day i'll care a little more, but i'm trying to learn the basics right now and in the middle of it all, I have to put these people to bed? I'm modding that out ASAP!
