Silverhawk170485: Command Modern Air/Naval Operations [url=http://www.matrixgames.com/products/483/details/Command:.Modern.Air.Naval.Operations]http://www.matrixgames.com/products/483/details/Command:.Modern.Air.Naval.Operations[/url]
It's a very complex Strategy-Game.
You can call it a successor of the Harpoon games.
You command air, sea and land units on a 3D globe which looks similar to google earth but with less high resolutions. But you can make your own overlays and add it in the game to get a more detailled map.
The game is very modder friendly so that you can create your own content. There is also a great and very active community in the official forums which supports the game with new missions, overlays and so on.
The game has thousands different real world units which you can command over several time periods. The units are only visualized by specific symbols. But this creates a atmosphere like you are sitting in mission control and giving orders to the units.
The game has a steep learning curve. There is so much to learn about how to play this game and the units and their loadouts because everything is based on real world data. So you can even call it more a simulation than a game. You even can learn something about modern warfare tactics. But once you get the hang of it, you can't stop playing.
The game still has some flaws but the developers are very active and release updates more frequently.
This game really has a potential on epic scale.
Regarding the DRM question:
The game must be activated with a key but it's only an offline activation.
Loved Harpoon. Clicked link. Saw the Matrix Games price. Fainted. Woke up and saw the price again. Fainted a second time.
Wish I could dedicate the time it takes to master games like this...
