Gaming on dedicated handhelds: Can any smartphone really compete?
I've yet to find a smartphone game that holds my interest more than a week or two. Game Dev Story, Plague Inc, Tiny Tower, Puzzle and Dragons, Cthulhu Saves the World; I lose interest pretty quick.
Meanwhile, I still play and replay great DS games like SMT, Pokemon, Castlevania, Fire Emblem, TWEWY, and Infinite Space.
I think the free or low-cost nature of smartphone games is part of the problem. They are disposable, and I have no incentive to finish them, partly because they cost me next-to nothing. No developer is going to create a 60-hour adventure as compelling as Infinite Space or Fire Emblem, then give it away for nothing, or nearly nothing.
Also, buttons.
