This is like they're all playing Ogres and Oubliettes with Discord, Spike, and Big Mac creating these characters as their counterparts in the games/stories that Spike the DM plans out and guides them through just like Dungeons and Dragons.

The best experiences of D&D happen when there's an amazing, stocked, well-planned, experienced, and charismatic dungeon master it truly does feel real even when sitting around a table with nothing but dice and a piece of paper with all of your character's info/stats written on it. Imagination and passion are powerful things especially when combined. If you add in motivation, energy, time, and money you'll get art, books, new inventions, and different ways to change the world hopefully for the better but it could also be for the worse.
