Well i'm not fanatic to Unity but i've got some points :

- Road editor : that's on the works for Unity :

- And for the water editor : it's just a shader.
In Unity , you could also create the mesh with the form you want for the river of your scene.
You just apply the shader and that's it.

I recognize that in Torque : be able to create pieces of water and modify them (size, shader parameters) in real time is a good thing.

Just don't forget some points :
- Unity script is very easy compared to Torque (for additionnal tools/ things you can use C# , no C++)
- how it's easy in Unity ot create things, and how good the workflow is (drag and drop physic panels on an object)

You can go to showcase of Unity and see how many thinsg are created by non programmers (or very beginners in programming) people.
But indeed, Torque 3D now have impressive editors , good shader library , great shadow management.
Now all it needs, it's like Far Cry editor : the same AI for ennemies.

Well , just keep relative also , that's good point to show others engines advantages, it can inspire others engines.
After that , even with such advanced tools, i doubt lot of us will achieve a big AAA title with lot of AAA textures, structures and characters
