Brass Hats is very much a game in the vein of Advance Wars or Military Madness. It's turn-based, you have your guys, you move them around, they attack other guys, they die, maybe you build some more, maybe you don't, and hopefully they kill all the bad guys. If there's something really witty left to be said about this subgenre of game, it ain't gonna be here and now.
What I love about this subgenre is the attention required from you is completely on-demand. Whatever other swarm of media devices you have ongoing in the background, your attention can shift seamlessly between them and this type of game, given its quick, turn-based nature. But games like this can be a little too simple when you have the brain cycles to spare. However, Brass Hats, with some small additions and adjustments to the overall formula, sharpens the strategy to a finely honed point.
