How else would you be able put your Wiiware games on your WiiU? The Wii never had online accounts, everything was tied to the physical console. That's why you had to pray your Wii never died, or else you'd lose everything. Nice job there Nintendo.
To be fair though this isn't a WiiU problem, it's a Wii problem that the WiiU has no choice but to inherit. The WiiU will have online accounts.
Not a big problem for me though, I have to keep my Wii anyway so that I can play Gamecube games. Rolls eyes. Would 2 generations of backwards compatibility really be that hard Nintendo. I have to keep my DS to play GBA games and my gameboy color to play my gameboy games.
