Captain Kwok's Space Empires Nova

[Captain Kwok]

I like the idea of putting them on the engines, but do you have to make so that the emergency points gained outweigh the movement lost from the engine being damaged?

If you've got a QNP system, you don't have to worry...
It will simply be a question of whether your ship is big enough that the loss of one engine (which may be less than one move point) is worth the bonus move.
