i was thinking....and...right now you can pnly place planets on a X and Y plain not Z will this add in the Z plain so you can have a planet orbiting one anather when the first is link roudning the top of it or boring the planet in a Oval where sometimes on the top sometimes on the bottom
Elliptic orbits are already in the game, you can create them in a system editor. They are just not created randomly, but random systems need a lot of work in a lot of other ways too. It's probably coming. Z-axis is a confirmed no - it may look cool, but it doesn't really add anything to the gameplay, while creating some complications with physics, pathfinding, etc... Real systems are pretty flat, so this approximation doesn't really hurt anything.
