Saga

Saga is a free-to-play massive multiplayer game that manages to “marry” the genre with RTS in a beautiful way. You can create your city and manage your resources and troops to lead them to victory. You start out with a basic set of troops and can get more through playing or buying more from the shop.

If solo playing is not your kind of playstyle then you can try Saga’s Co-op mode or compete in PvP and Tournament modes. Either way, if you like RTS games like Total War and Stronghold, then Saga is a multiplayer game that you should definitely try.
