Two things i liked were, Soos' grandma, and her comment about his grampa, and on the game's start up menu, for dome reason a choice, once i Googled it, was the name of a famous Japanese artist...
Soos' Grandma is hilarious. His life is my soap opera. I liked two more references. When Soos admitted he didn't know whether to call his "girlfriend" Gif-any or Jiff-any, which is of course the uproar caused on how to pronounce gif.
Also when he read the sentence in the game. "Anything can hadplen" or something like that, which is making fun of how bad translations from Japanese to English can be.
Gravity Falls and Scooby Doo: Mystery Inc is a crossover that should have happened.
