[quote name='Quackzilla']Only one of those games is not a port or a sequel.
PSP actually has more original games than DS.
Coded Arms
Lumines
Mercury
Death Jr.
and a few more I can't remember off the top of my head.[/QUOTE]
Uh, touchscreen? He was just mentioning some of the more popular unreleased DS games (he didn't even mention Metroid Pinball, Trauma Center, or Phoenix Wright).
If you want to delve into the games already released by including Lumines and Mercury, then you'd have to look at FTM, PacPix, and Yoshi.
Fun-factor, Graphics, and Overall goodness are different than originality, but if you're debating that, then the DS wins 8 times over.
