So while I like my DM, it's kind of hard to say that our game has a consistent story and that she legit decides everything on dice rolls. Oh you want to persuade that character? Yeah, that depends on my dice. Oh, I need to know if this NPC will respond to something. *Dice.*

"It's on my dice if anything you say to this character gets through to them." Like DUDE please just make a decision without dice. 

Edit: It's a one on one campaign. A roll they'll make is to see if an anime character will show up or not, even though there's been no hints of such character in this world before and it's a completely different source media.
