I've played this game for 9 months, never once came accross a good wiimote player, but I never play SnD.
The auto aim for dual analog was ridiculous. Still, I did pretty well with the remote. I hope they toned it down in Ghosts.
Oh, and there will be no DLC as long as Activision in not on the eShop. I don't think it has much to do with sales. They have zero eShop presence and DLC has to be on the eShop not in app.
