Well all your armies are hidden, and the battles are largely luck based since you have to choose for yourself what order to play your soldiers without really knowing what your opponant has (though there are some cards you can play throughout the game to peek at another players armies). So it's definitely not zero-luck.
The open information is what territories each of you have and can attack based on your own territories, and the number of soldiers you've got on each territory (though again, these will be face down so you won't know what type of units your opponant has).
Not having played the games you've mentioned though (other than chess) I can't really compare it to them. Sorry!
