we use the number of closed tasks/user stories but also came across people gaming those too. Lower the scope and cut corners (shitty design, superficial meaningless unit tests, ...).

I wroked in a company where the CTO is tech illeterate and everyone is gaming everything, I worked somewhere else where the CTO is the smartest and most tech savy person I have ever met and gaming anything there becomes obvious and people are shown the door out of nowhere (yet for a good reason).
