Understanding how gamification can be leveraged to improve collaboration or encourage certain online behaviors has definitely been of use to me in my work. I see gamification as something falling along the spectrum of engagement strategies. It is unfortunately named, because many leaders see gamification and think "games" which is a completely erroneous assumption. Gamification is a method of leveraging game elements to achieve business goals. As a result of this view, many leaders in B2B view gamification work as something nice to have that might be fun for employees but which is entirely optional. But to more directly answer your question, certifications are meaningless without practice, so, no, it hasn't really had an impact on my career. Applied learning trumps certifications of all kinds in my opinion.
