I've been realizing every so slightly about how there's really a lack of variety in terms of ORGANIZED activities you can do with your friends (in singleplayer).
I was thinking....why is paintball or airsoft not an activity? Think about it, a great way to increase your shooting skill stat while enjoying the thrill of combat as opposed to the simplicity of the Ammu-Nation target range.
Another idea I was having was the idea of batting cages, perhaps have players compete for the farthest total combined distance of all their hits or something. But THAT activity would be a good way to up your strength stat.
Anyone else have any great ideas they'd like to share?
