Blender City engine in Unity 3d(EN)

Hello everyone,I had some problems to create a city environment for my unity 3d game.After many Google searches I found the Procedural City engine,an awesome software,but a bit expensive for me(the cheapest cost $495).So I think don't exists one free open-source alternative?After other Google search I found the Blended Cities plug-in.

• What is it?

Is a Blender 3d plug-in that can create a fantastic city with few clicks.

• What can I do with it?

This video show a city created with Blender Cities plug-in:
