Great game, one suggestion: In multiplayer, have an option to have two players play against each other on the same computer. They can take turns entering orders, and battle that way. That'd be awesome.
Oh, and aren't the rocks we're mining gems in themselves? Clearly, if there's an infinite amount of them, we can just pick up a few, and give them to the blacksmith.
Why won't this game match me with someone I am actually allowed to attack? It would be much appreciated if you guys would allow you to attack anyone, no matter how many troops you have. 2:3 upsets are possible! Otherwise, great game.
