Solid gameplay, mostly replayable and interesting because of the well-programmed AI, but the overall experience suffers from the hedious artstyle that leaves a bad first impression.
SotS is an turn-based strategy game, inspired by the perfect Advance Wars series, which are only playable on Nintendo devices. The former is not as deep and doesn't follow the 'grid rule' (like a chessboard) like the latter. You move units anywhere within a certain radius, and you are limited to five actions per turn (in contrast to AW, where you can spent a whole lot a time in one turn moving your whole army). Games like these need a good competitive AI player to fight against. 17-bit knows and shows that.
The downfall is when you have trouble overseeing the battlefield. The artstyle of the units tend to blend in with other units and surroundings. I often didn't notice that I had another unit behind my archer, making me reload the last autosave. The free-movement also makes it difficult, at first, to understand why you can't move a unit between other units or objects. Even the AI seems to fidget around specificly with that. In the end, these annoyences aren't gamebreaking, but they do leave a bad first impression, which means you'll get used to them.
The 'stretching animations' and the corny - sometimes fourth wall breaking - jokes aside, I can full-hearthedly say that I enjoyed the music, challenge and general length of the game. I didn't check it out myself, but apparantly the multiplayer is really fun too. I should warn completionists, though, for more than 50% of the achievements are either time-consuming or just difficult to unlock because they require you to build specifc setups/arrangements in the battlefield.
