Just to add fuel to this fire: Skill based gaming actually has a very strict set of rules it has to follow to not be considered gambling. Perhaps chief among them (and I am not a lawyer) is that the chance to do well at the game must be equal for all participants, which makes a lot of games physically impossible to use such a system.
However, that is not at all related to @anonymous_user_c930a980’s need to hire someone. It’s just interesting 
There’s plenty of places skill based gaming CAN be applied. I just wanted to make sure nobody reading this runs off to slap a gambling mod onto Counterstrike
