Okay so today I was getting all excited about the game and imagining all the cool scenarios we're all going to find ourselves in and one in particular came to mind.
When building large ships, like battleships or cruisers that are mean't for 15-50 crew members, be able to install an emergency broadcast system. A system which would be activated by pressing a button or flipping a switch and when it's turned on, all speakers connected to it would ring out "ALL HANDS TO DECK, MAN YOUR BATTLE STATIONS" or something cool like that. It'd be both aesthetically pleasing and it would serve as a way for a captain to communicate battle orders to his crew in a timely and easily received manner.
You could even add a functionality that allows for VOIP over an intercom system so that Captains can broadcast orders to the entire ship.
Just an idea, let me know what you think!
