24. Ultimate NES Remix (3DS)Now what I mean by "completed" is that I unlocked enough stars to open all the levels in the "NES Remix 1" and "NES Remix 2" categories. Then I beat all those levels. There's still plenty of game-specific challenges left to play through, though.
Just got the game this afternoon, and I haven't put it down. I had to charge my 3DS eventually, so I stopped. I'm freaking loving it!
