Ironically, Advanced Wars and Fire Emblem, Nintendo's tactical RPG entires, can go on touchscreen just fine. A few others (such as Elite Beat Agents) would arguably do better on the Smartphone platform.
But this is definitely the minority of the games that Nintendo makes. The thought of playing something moderately fast-pace like "Mario Tennis" on a touch screen scares me. There isn't enough precision, and no touch screen is as responsive as a controller yet.
The major brands: Mario, Zelda, Metroid, Kid Icarus, Donkey Kong require speed and precision beyond that of the touchscreen. Let alone the issue of blocking the screen as you play the game.
