This is such a small thing, but I still want to ask it!
What if there was a mechanic that allowed you to leave small scraps of paper with whatever you "wrote" on someone else's insurance returns?
I've gotten in plenty of gunfights where at the end I stash the other person's gear because they were doing a quest (ie blueberry boy Peacekeeper quests) and thought it'd be pretty sweet to leave a note like "I got you man! Good luck on your quests, sorry for shooting you" and things of that nature.
Obviously the darker side is that it gets used as toxic trash talking mechanic, but let me know what you think!
TL;DR: A Mechanic that lets you leave notes in other people's insured stuff so you can "talk" to other players. Thoughts?
