Gta Online has one of the most interesting approaches to a possible Litmus test i have seen:
>Get into a public Lobby
>You get a notification pop up about someone making a sale on the map, plus their current location as long as they have the cargo.
>In theory, you get money and xp if you destroy the cargo, so you should be feeling encouraged to do so
>However, xp is meaningless after lvl100, you get rewarded 5k which is its 99% of the time not even enough to cover the costs of explosives needed to destroy the cargo
>Meanwhile, the other guy could potentially earn up to 500k-1m depending on the business.
>It is most likely you won't even know this guy at all.
>So, you can either walk away and do something else more worthwhile, or be a dick and attempt to destroy their sales for the lulz, crippling progress that can take hours or days to get back.
You got to be quite a dick to fuck someone elses sales.
Sometimes the whole lobby would outright fucking hate you, and hunt you down like a dog and spawn kill you until you leave. Not even going passive will save you, people will try to aim at any vehicle you so as much approach to make it explode and take it with you.
