I'm not surprised the game is more popular either, but selling in one week what its 3D companion has sold in two years is just mind-boggling. Of course, I'm not saying the game shouldn't be selling so well; it's a great game and I love it. I'm saying the opposite: I'd have liked to see Super Mario Galaxy sell better! I guess when looking at the worldwide sales then it has achieved a good number, but I'm just worried that this doesn't bode well for future 3D Mario games. Yes, I know that Super Mario Galaxy 2 is just around the corner, but that game was announced before NSMBWii was released and Nintendo knew that 2D Mario can still sell on a home system. So I hope to see a continuation of both types, if Nintendo can handle it.
