One of the greatest things about the mobile market is the reappearance of older, single-player titles that are now being introduced to a new generation. Tablets and smartphones are quickly becoming go-to gaming devices offering not only more powerful processors and bigger screens but access to the internet and huge stores of digital goodies. Recently, I've been playing through titles I've missed, like Broken Sword, a point-and-click adventure game from 1996. Touch devices are proving to be perfect for many older-style games. We're simply replacing the mouse with the finger, and the move feels natural.
