Are there any educational resources or middleware for creating Real-Time Strategy games in Unity?

I am exploring doing an RTS in Unity. I have heard of some experiences with the Last Bastion Games RTS engine, but the reviews were mixed. It is also a little too expensive for my purposes.

Do you know of any resources on learning to make an RTS game in Unity?

Any middleware or projects that can be used?

Thanks

Here's a pathfinding system which I have made, and I used it to make an RTS demo a couple of months ago.

A* Pathfinding

You can use that to make the moving of your units a bit easier.
I don’t know of any “learning to make an RTS” resources though but I hope this will be of some help.

Martin Schultz posted his Generals project on the Unity forum, which might be a good starting point.

Ideally you'd create a level editor that is highly robust, but that can be quite challenging too, especially since we're already sitting on top of an engine. It's a good question though, because Unity doesn't give you the feel of a well structured game if you're coming from Ogre or other engine experience. However, it is!

(Sorry ramblings.) I'm working right now on an RTS style that's making use of prefabs, A* setup, and other various logic and it's coming along nicely..

Unity Prefabs has an RTS camera kit that may be useful.
