This is just a terminology thing.

I think we could use better terms for the flight modes. As "arcade" just sits on top of physics anyway, why not give it a term in the context of the game (role-playing!)? Something like "Navigation Assistance Computer".

Just call a spade a spade, mate.

so, you want a NAC? That was a great band....

MY SHARONA!

I agree. 'Arcade Mode' does not sound like it would fit into the context of the story canon. And it DOES sit on top of Physics mode, using the same rules and thrusters. The computer just does all the thruster micro-management for you.

I second calling it something like 'Computer-Assisted Mode' or something.

Though, calling it 'Arcade' is just way simplier, it's just not as descriptive.
