I was going to release a video like this about a week ago but it took me until now to figure out why my  space ship code was crashing in 1.7.0.

In case anyone else has this problem upgrading from 1.0.3 to 1.7.0 try increasing your integration level in the vehicles datablock.
In my case I had to double it.

As for the video it shows one of the key concepts of DayOfWar , independent gravity.

Both moons have there own gravity.
The gravity is very realistic.

The video doesn't show this but.
Ridged shape based objects can be put into orbit.
I found that out by accident.
I was moving a planet around and forgot there was a wheeled vehicle on it before I moved it and was amazed to see it fling itself around the planet.
It made three complete orbits before crashing back down to the planet and ,because I had it set for collision damage, it exploded when it hit the planet.

I will get some videos of this later and post them.
