The few times I have tried a more impressive game on my phone, my overriding thought is ‘why am I not playing this on my PC?’. Phone controls, screen size, and processing power suck, so all but the simplest games meant to hold your attention while you are waiting at a doctor’s office don’t optimally work there. And for a doctor’s office lobby, I want something I can have fun within seconds of starting and feel satisfied with only minutes of play.
