Pickleball with real pickles. But what would the paddles be?
That’s the required headgear.
You’ve confused pickleball with Pastaball, the official sport of Pastafarians everywhere. Though in most Pasta [del]denominations[/del] shapes the preferred headgear is the one without the handle. More like this: https://www.amazon.com/Collapsible-Colander-Flyboo-Strainer-spaghetti/dp/B071H53GSR/ 
Wish we had a sheepish icon because I used to play a variation of javelin catch with my buddies in high school. We would stand near a marker and dodge the incoming throw. I’m always amazed after all the things we did that none of us were seriously injured or killed.
In that vein, I present:
Roman Rules Duel Tag, whereupon two opponents square off at 20 paces and have their seconds light the ends of a Roman Candle and you try to hit your opponent with a flaming ball of pyrotechnics while avoiding same. (Yes, we really did this, and had made handles in wood shop with a clamp to hold the Roman Candle so you could “aim” it.)
Flaming Nerf Ball. A simple game of catch using a medium size Nerf ball liberally soaked in lighter fluid and set alight. First person to drop the ball, get burned by holding it too long, or intentionally missing a catch, “loses.”
Thank the Stars Youtube wasn’t around when I was a kid…
You reminded me of a game I’ve witnessed but was never drunk enough to take part in:
Flaming Toilet Paper Hacky Sack- soak a roll of toilet paper in lighter fluid, light it and kick it around until it completely unwinds (which leaves lovely flaming trails, especially at night). If it hits the ground someone has to pick it up and put it back in play.
My teen pals and I used to have Tennis Ball Mortar Wars - Two groups of 3-6 kids each armed with tennis ball cannons, lots of tennis balls, and plenty of Ronsonol form up about 1/2 a cannon-range apart. You can fire at high angle like a mortar or low angle like naval gunfire.
We had “obtained” quite a supply of GI sandbags that were good for building impromptu firing positions.
Incoming!!
It’s a wonder no-one in our gang was crippled by our various escapades. Remember, we did all this stone sober. Hemingway would’ve been proud of us.
Here’s one we used to play on slow days in the U.S.A.F.-See-Thru Frisbee. All you need to play it is a handful of idiots and a small window pane.
Filletity - carving up various animals to rid the meat of bones
Big Game Haunting - dressing up as a ghost, hiding behinds rock/tree/bush until a deer/elk/bear/elephant approaches, then jumping out and yelling “BOO!!!”
SCUFA Diving - Self Contained Underwater Farting Apparatus. Air hose goes from your rear end to your diving partner’s mask and vice versa. First to have to surface loses.
Aneminas - shoving slow moving, tentacled sea life up one’s nether regions.
I’ve always wanted there to be a skit about how the Scottish tried to drive off the English with a bunch of golfers, showing dozens of them teeing off toward the advancing column and having them flinch a bit but then continuing on almost unbruised.
Unbruised? That was the heyday of polyester double-knit clothing for kids. I can’t count the number of times I took a high speed flaming tennis ball in the chest. How my or somebody else’s plastic shirt never caught fire (much) remains a mystery to this day. Must’ve been a case of “Too stupid to live; too younf to die”
Model Airplane Tell - one person stands in a field with an apple on his (good bet :D) head. Somebody else flying an RC model airplane tries to fly by at speed and knock the apple off.
I feel as if I have to mention Al Jaffee’s piece in Mad magazine from 'way back in 1974, Basebrawl. It’s not just a one-liner – Jaffee re-imagined the “gentle” sport of baseball as a really rough-and-tumble high-impact event with enormous potential for injury. For instance, the batter gets to keep his bat (which is a high-tech metal implement) and use it as an offensive weapon as he runs the bases. The basemen, in turn, get to “tackle” him out. The baseball is made of steel.
Classic Road Bike Parkour- A timed course is arranged with suitable obstacles that have to be jumped or ridden over such as garbage cans, picnic tables and concrete rails in which opponents try to finish the course without getting off their vintage 10 speed. Acceptable models would be anything with downtube shifters like Peugeots, Bianchis, Sekines and the like. Helmets and crash gear optional.
Rockminton- With badminton rackets, try to swat small stones back and forth. The rackets don’t last very long. Play until one player has no strings left in his racket.
Frog Crucifixion- Not as much fun as it seems at first. Hard to get enough frogs to play for very long. There’s also a hazard of pissing off your Christian neighbors.
Traffic cone bombing- Insert a firecracker’s fuse (big firecrackers are better) into the side of a cigarette, and tape both to one end of a hibachi skewer. Using a pocket knife, make the other end of the skewer into a hook or a T. Find a place with a utility repair in the street next to a lane where cars wait for a traffic light. Light the cigarette at the bottom of the skewer, and hang the other end inside the top of a traffic cone next to the waiting lane. You can do this from your car, while you are waiting for the light to change. Retreat to a place where you can watch what happens. If you’re lucky, the bomb will go off several minutes later while somebody is next to it. It’s fun to watch the startled driver try to figure out what just happened. No harm done to the cone or the driver.
Hair Curling – participants wash their hair and roll them up around regulation 40-pound Curling Stones, then try to stand up. Last survivor wins.
I’ve played tennis with golf balls. It’s actually quite fun since the velocities get higher even for the mediocre. And we didn’t break any strings the few times we did it, but if I tried it again I’d demand football armor.
Growing up, playing baseball with a Superball was not uncommon. (1966-71)
Hit hard enough(usually one of the older players), the ball would shatter. Otherwise, infielders stationed in shallow outfield was normal.
Superbaseball was great! Thanks for the reminder. It also made a real impressive big league THWACK sound when you connected. Remembering that we did this back when even kids’ baseball / softball bats didn’t go “twang!!!” Gosh I hate that noise: jus’ t’aint right. 
Supergolf is kinda fun too. Can be hard to find the damn ball again though.
Speaking of tennis, another game my brother and I did more than a few times is 4-court tennis, at a place where there were 4 courts of tennis that were often unused at night, with 2 sets of 2 courts divided by a chain link fence (and the entire thing surrounded by another chain link fence of the same height.) Each person was on one side of the fence. We never got the rules down solid but one commonality is that the ball could not bounce out of the court once it landed (although careening off the fence was allowed).
And, totally against the spirit of the thread, after a few games we decided that we were not allowed to jump over the nets on our side due to danger.
One word: CalvinBall.
