As far as starting over, I have started over many, many , many times. Some times it is my ineptness, sometimes it is adding a mod the talented modders on this site put out there, or wound up with mod soup that does not work. I felt a lot better when I read some very seasoned players are still in 1939. I am sure they are playing with 100% realism. If this is your type of sim hang in there. Everyday I get into SH 5 I learn something I did not know
