I can, especially with 3 or more people playing with you, that's one of the major positives about NintendoLand and NSMBU.
I do see your point, not enough top-notch 1st party titles from Nintendo. They did say they planned to support the console with games next year, but you have to remember that there are a number of highly anticipated, excellent games coming out for the 3DS aswell within the same time-frame.
