unreal absolutely does have support for this type of game. It is really a smattering of different loosely coupled tools that you can bring into the project, or roll your own. The star is absolutely the rendering engine and visual programming tools IMO.
Unreal really excels at action games, but you can absolutely implement custom camera RTS controls and such. Batteries included but replaceable.
The question "does X engine support this kind of game" is a bit.. off. You would be amazed at how many features these engines pack in. However: You would also be amazed at how NOT "plug and play" they are. It still takes a TON of effort and custom code to make a sophisticated game.
