As I was asking for a more strategic MMORPG, the makers of Dreamlords The Reawakening wrote me to tell that their MMORTS just released this week. And it's free-to-play, so I tried it for a while.
Dreamlords combines a 3D game downloadable client game part with a 2D browser game part. In the browser you manage your patria, your country. You do things like building housing, putting workers into various buildings, and doing research. In the 3D client you go adventuring and questing in a RTS-like gameplay. Winning victories in RTS rewards you with items, which you can either use, or transform into things useful for your patria, like gnosis, which controls how many inhabitants you can have. The game has lots of options and is relatively complex. And apparently at some point you can do PvP against other players.
The idea is nice enough, but the execution isn't all that great. Movement in RTS is slow, and the RTS fights not very interesting, at least not at the start of the game where you only have your dreamlord and 3 soldiers. The game manual is very short and often leaves you wondering what you are supposed to do. But then I'm not a big fan of real-time strategy anyway, always have preferred turn-based. So as Dreamlords is free, you might want to check it out for yourself.
