RNG - Really Nasty Grind.

I'm not a fan of it myself, all it does is to give [The Lucky] instant gratification at the cost of [The Unlucky].
But maybe it also feeds some sort of gambling addiction? I dunno. It "is" a form of gambling, your stakes are your time and the rewards your payout, but I'm not sure if it has the same effects. Is "Just one more run..." a thing?

Personally, I just stopped bothering with it. Without a clear goal line, I'm not even moving.
