Well I came across this article
http://www.space.com/12529-earth-2-moons-collision-moon-formation.html

A good read. But it basically says that the mars-sized object impacted forming two moons. And overtime eventuality the smaller moon became unstable in it's orbit and pancaked into our current moon scientists say it could be why the side that faces away from the earth is so different than the side that faces toward the earth. I would like to hear you opinions on this theory and how likely it could have been.

Nice little mock up in Space Engine but you should do something like this to Earth

Doesn't really take into account plate tectonics or how Earth would really look, but it does give the look of a "dead" world.

I thought mass, volume and velocity were the key ingredients when it came to moons, not the type.

Type is determined by mass, at least in SE.
