I don't think it helps that they came out within three months of each other...
They did? Wow, maybe they should have delayed 2.
Yeah, and that was the biggest problem. There was almost no point in playing NSMBU if you had already played the other games.
Yep. I remember one of my friends getting NSMBWii instead of NSMBU because NSMBWii, because she felt NSMBU was just more of the same, so why not get the cheaper one?
