DnD? As in Dungeons and Dragons? 
I played that before 
It’s a fun (and funny) experience.
I have an idea for a contest and I call it Coming To Life.
Basically it involves fictional characters in that story popping up to the already fictional character’s reality, be it a video game character or a movie character, or the complete inverse where the player gets sucked into the gaming world instead.
Jumanji vibes, but it doesn’t have to be life threatening for it to be enjoyable
A few prompts I can think of:
A mysterious force brought the MC from the game world to the real world, where the player (LI or something 
Idk) and his/her favorite video game character come to know each other.
