This could actually be used for skills:
--> Like GF Boost in FF8
--> For a Limit Skill. You have a set amount of time to press C, and the more you press, the more damage the skill does, or the more times it strikes ( something like Squall's Renzokuken, well not exactly, you got it anyway...)
-->Many minigames. (Soda guzzling contest, yay!)
