I have to say that I really like the way 'academy mode' sounds, perhaps that could be it! Ensign mode would be great too, but I wonder how many 'ordinary people' actually know who an ensign is.
Regardless, thank you once again for your invaluable input!
We will soon be stepping up our testing as the release draws near, and I will be posting a separate thread to ask if anyone is interested in giving the game a try and sharing their feedback.
