The touch screen. The two screens. The end of the Game Boy line. These are the things that the Nintendo DS was known for when it launch.

Without a strong launch lineup, and with the announcement of the PSP, the first serious competition in the handheld market for more than a decade, few had much confidence in the two-faced bastard child. People pointed at the Game and Watch and Virtual Boy and thought that Nintendo's portable domination was over.

But then, the hits started coming. Metroid. Mario Kart. Castlevania. By 2008, the DS had arguably the best lineup of any handheld in the history of our medium. Pokemon, JRPGS, portable remakes, side-scrolling revivals, even adventure games found perhaps their only remaining home. Niche games like Phoenix Wright and 999 found shelf space next to Nintendogs and Professor Layton.

In the end, it was the incredible library that became the legacy of the best-selling portable (and perhaps best-selling CONSOLE) of all time.
