As many know nintendo has started Re-Releasing Wii games onto the WiiU's virtual console.
Before you would have to access the "Wii" menue on the WiiU and start games from there using a wiimote. Nintendo has now started adding Wii games (with function updates) to the WiiU eshop.
Mario galaxy 2 was the first to be added with the "Metroid Prime Trilogy"
releasing this week in Europe.
Though the games them selves are the exact some of the VC version will allow you to use the game pad and pro controller and and instead of going through the Wii program the game will be downloaded directly to the WiiU home pages.
Anyways if you didn't pick the Trilogy up at launch or were unwilling to pay $60 for a used copy you can now pick it up for $19.99 (or $9.99 on sale).
