Doesn't look like the touch screen really gives an advantage really over Mouse and Keyboard. Sure it's more "intuitive" but it just ends up looking more cumbersome and the gameplay looks really simplified as a result. I'm sure once the novelty of the interface wears off, it'd be quite a mediocre game.
Then again, with the sucess the Wii has, maybe I'm completely out of touch with what is the future of gaming.
