Answer:
The main similarity between these two games lies on their objective, which is to "mark" your opponent
Step-by-step explanation:
Garosella was a competitive game played among Arabian horsemen in the 11th century. In this game, riders would try to throw and catch small clay balls. If one of the players missed the catch and got hit by the ball, it would crack open, releasing a heavy perfume that would scent the horseman for days, marking him as a loser.
Similarly, in paintball, the players mark their opponents by hitting them with with round capsules filled with paint that break upon impact, which are shot from an air weapon, leaving a visible paint stain and marking players as losers.
