Minigames and side activities for events, downtime and player retention: football and basketball pitches, bowling, paintball, bumper cars, gym routines and one-off event scripts. Most of this archive carries an ESX or QBCore label and a large share is also listed as standalone, so the same activity usually works on either framework.
Some listings bundle a map with the script, so you get the arena or venue as well as the gameplay loop instead of placing one yourself. Check the product page for that, and for dependencies such as PolyZone or ox_lib where a product lists them.
An activity earns its price only if players find it and it cleans up after itself, so check where it is placed on the map, whether rewards and match length are configurable, and whether it stays synchronized for spectators. Most product pages link a preview video.
