The ONE problem I have with Ingress...
... is the neck strain.
UGH. You ever just get into a gaming groove, and you literally go for hours, not realizing what you're doing to your neck, and the fact that you've NEVER dropped your arm to relax, not even once?
I've done this now so many times, giving myself a cramp or two because I've been hyperfocused.
