I shoot for fun in my old age, and I can't think of any thing more fun then something like the Texas Star or similar targets.
We were getting cocky with our clubs Texas Star, so they started putting a sheet of plywood on the top half so we could only shoot when the plates were at the bottom.
Which if you ever shot the Texas Star, you know shooting the bottom plates first, gets the targets spinning faster.
Moving targets are a heck of a lot of fun.
Rifle movers aren't as much fun unless you vary the speed, or have stop and go targets down range.
A game I haven't tried yet, but want to is where you have a cut out target of dangerous game that comes toward you at relatively close range and you have to make a killing shot using a heavy Africa type rifle with full power loads. Seen them shoot those targets on TV, they look like a heck of a lot of fun.
