7. Tiny Ninja
In all honesty, Tiny would make for a better sword-toting companion than Link (and easier to install on your phone). In Tiny Ninja, gamers are tasked with the duty to help the would-be ninja to pass his "Chuunin, Jounin, and Kage" level tests. Though the learning curve progressively becomes more challenging, Tiny learns what it takes to become a master, without making your dollars disappear.
