Could there be color schemes for this game. Being able to change the Background color and text color would be cool. I think I remember some old Telnet programs that I would use that would allow for customization like that.
Next level, incorporate a scheme that is locked until someone does a certain thing in the game. Maybe it is locked until someone defeats the dark lord then you can customize your colors again, until the timer is up and it goes back to default colors. Say 1 hour, 5 hours, 24 hours?
