Yeah it would probably require the touch screen etc. I can imagine playing games like Samus Returns, Luigi's Mansion 2, Fire Emblem Awakening, Monster Hunter 4, Animal Crossing New Leaf and Mario Kart 7 on the Switch's bigger screen. There are a lot of cool gems on the 3DS that I feel could go well with the Switch.
All these game series are getting or already have Switch installments though. Course they wont be the exact same game, but being playable on the big screen is an advantage you can look forward to with the Switch iterations.
