This isn't tactics at all
Okay, since my score probably has a lot to do with my recent experiences with this particular genre ill be explaining my given score in a little more detail.
First off, this has nothing/little to do with tactics, chess is a game about tactics, this is a game of chance and luck, it has more of a resemblance to casino games than actual strategic insight.
I'm tired of games claiming to be about tactics where even the best tactic can fail due to terrible luck, I've played a lot of such games like Fire Emblem, Final Fantasy Tactics, Ogre battles and more, and frankly, none of those are very tactical, its mostly a lot of saving and loading and hoping the odds are in your favor, unlike actual strategic games like Advance Wars and such, where the result of a battle isnt based on who gets the best roll of the dice.
Its like when you play risk and send 20 dudes to kill one defender, you roll 1-2 20 times in a row, and he rolls 2-6 20 times in a row, you lose, to one defender and your entire strategy is fucked up because of bad luck, I don't see who would think of this concept as "fun" or "strategic"
These kinds of games aren't about strategy, they're about luck and if that was enjoyable I might as well sit around playing with a dice-roll generator feeling happy whenever it generates a good number.
The game itself though, other than claiming to be something its not, is well made in terms of visual and sound design, the programming is solid and its a good game if not flawed in concept.
