I can’t bring myself to download a first-person shooter game on my iPhone anymore, just because I know I’ll get sick of it before the third level. Its icon will sit there on the screen, its data will languish on the drive. Delete it? Can’t. Might get stuck in an elevator, beat all the games I actually like, and have nothing left to do but count the minutes. Nothing against the companies that make these things; I just can’t abide any game in that genre that won’t let you touch physical buttons.
