I enjoy micromanaging certain things and have found I can get extra movement by moving my ship to a planet's shipyard and then launching the ship out the other side of the planet as long as I am going in the right direction.
I sort of treat this as a gravity assist using the angular momentum of the planet just like NASA does with the space probes. It does come in handy.
I can also see where some would consider this an exploit. I'm pretty sure the AI never does this.
I also realize it isn't even done realistically for a gravity assist as it is say from left to right on the map rather than consistently clockwise or counterclockwise around the planet in relation to its star.
So, anyone else do this, like this, like my take on it, hate it, ...etc?
