The time has finally come and you can start catching 'em all. Pokemon GO is now available in the US for everyone to download and try to be a Pokemon Master. Or maybe just see whether all the fuss and hype matches up to reality. Available for free on Android and iOS, the augmented reality game will, of course, have its fair (or unfair) share of in-app purchases. But Pokemon fans might not mind in exchange for leaving out their childhood, and not-so-childhood, dreams.
