Sure thing, will do. I'm currently looking at a platform called Godot, but i have no idea what it can do yet and there aren't any RTS-like games in the list of showcases yet.I'll be searching for such a platform as well. Please, could you /pm me (and any other interested party), if you ever come across such a platform. I'd do the same.
