Hi Andy, trust me as soon as I am comfortable with the engine I will release some youtube vids.
I am working on the editor atm and having a huge headache getting automatic terrain blending working between the 5 or 6 different tilesets I plan on using.
I must stress that this is very early Alpha stage and that a project like this will take me a long time to complete by myself, so vids and images might be a while off yet.
