I put the Oblivion dialogue wheel on a gun. Every time you reload, you spin the wheel. The four quadrants correlated generally to major components of the gunplay, such as fire rate and damage. I prioritized making it absolutely goofy, so something increasing projectile count greatly increased projectile spread. Good luck hitting anything!

          The original Oblivion wheel was kinda bad and usually had a "solution" -- I didn't want players sitting for ten seconds trying to map out the perfect wheel, so the wheel spins at random (well, part-random) after every selection. Each reload is a die roll, and hitting a good combo of weapon stats is gonna feel really good, but only for until you run out of ammo.
