GTA: Royal Offense 2
Someone says that the best defense is the best offense. This might be true as you need to start on defending your castle before you can start with your economy. As your economy grows then you can hire better defenders.
At least, this is true in this second installation of the game. Enemies are attacking, but you would need to start with your economy first. Sending just enough men to defend the country. Once, you got rich then you can make an all out offense. The game gets harder and harder as you make some progress. The game is played with a mouse.
