Gamification - have you guys had any $$$ boost after implementing it? [poll]

Hi IHs,

I've heard quite a bit about gamification / interactive tutorials in apps.

However, my biggest concern is: is it worth it?

I want to implement interactive tutorials, in which people learn by doing (as opposed to static tutorials, where you just watch).

But of course, this is definitely not an easy feature to implement. So again - is it worth it? What has your experience been?
