Unified: Unity Of Command Patch/Sale/Demo

You will recall that one of Comrade Gillen's many, many, many returns from retirement included this Unity Of Command review, in which he reported a strategy experience that was "accessible yet deep, attractive and with an AI which teaches you the core of the game by beating you around the head." Despite that kindly recommendation some folks thought it was a little pricey to take a gamble on. And yet now there's a sale, and also a demo. So there's really no excuse for you not to take a look, is there?
