You will have to be more specific. A rts is complicated, especially when it comes to moving groups around.
So, I want to make an rts based on games like Starcraft and Age of empires, mostly. I was planning on isometric view but decided against it so I'm going for a top-down perspective now. You would have an HQ where you can make workers, stockage area for wood, metal and berries and your basic military units building + upgrading. That is the basic idea.
