I do agree though that the style would be incredibly "cutesy" for a console/PC game, but underneath it's actually a really well balanced strategy game, like a much faster version of chess almost, or a really complex version of rock/paper/scissors.
It's just a mobile game like Angry Birds, to while away the time on commutes etc. I'd argue that WoW is way more geeky, considering the insane amount of hours and effort and money you need to put into it.
