The long-awaited North American launch of the Nintendo DSi is finally here. The camera-equipped iteration of Nintendo’s popular portable system hit US shelves Sunday morning, trailing its Japanese launch by nearly half a year.

Having to wait five months for a new platform? What do you think this is Nintendo, Europe?

A new system launch ordinarily means a flood of new games at retail, but the DSi’s exclusive debut lineup is strictly available through Nintendo’s DSiWare downloadable store. However, the new-fangled system will play the newly released DS game Rhythm Heaven just fine. For more on that title, check out the video review below… Enjoy!

This unusual music game is as satisfying as it is strange, but the high difficulty limits its appeal.

Score: 7.5 / good
