well..... most WiiU bundles come with two games (SM3dWorld+Nintendoland; NSMBU+Nintendoland etc.) or a game and a controller (MK8+Wiimote). $ 300 seems a fair price, considering that competitors at best offer only one game.
Even so, I do believe Nintendo should drop the price to $250. Not sure if they can afford it, specially when it does seems that every home console maker is either selling their consoles with a loss or just even, trying to profit from software sales.
