Have Metroid Prime 1 for the Gamecube, bought the Trilogy on disc for 70€ at the end of 2012 shortly after buying my Wii U (didn't have a Wii).
I bought the Trilogy digitally for 9,99€, because I really like the convenience of just starting a game without first having to pop in the Disc, especially if I don't have to go into Wii mode first.
I'll play it in march, as I'm a little time constrained at the moment.
Well it does go in to Wii mode, it just bypasses the menus and boots the game directly from storange :P
NIntendo pretty much took a page from the softmodders handbook for this lol
