The idea is good and even natural since we use devices daily, but it has more complications than benefits. Some games took off and soon became saturated, like Angry Birds, Cut the Hope and Candy Crush for example. All in the same freemium style and with levels. Larger game ports don't take off because of the battery and heat, not to mention the ergonomics that don't help. What I played a lot on my smartphones were emulators, I was able to finish Pokemon and other games that I couldn't play because I didn't have a console.
