Somehow combat is even worse that Settlers 3. The graphics aren't nearly as charming. The noise of the UI is aggravating. The cutscenes are cringe. Play any other Settlers game.
Whereas the Settlers 2 was a colony simulator with hints of a RTS, the Settlers 3 is a RTS with hints of a colony simulator. That would fine if it weren't for the clumsy unit controls.
