This has been occupying a lot of my time the past few days. Beautifully done game, basically an old-skool war strategy game. Some extra features compared to the older GBA version, but overall the same basic gameplay. Improved massively with being able to use the stylus, and move all your troops around very easily. A lot of time could be potentially spent on it.
One of the many things I like about it are the icons that symbolise the different kinds of army units. They are like little chess pieces, carefully drawn and thought-through. After a few hours play each is burned in your memory.
