I never played the games but was able to pick up enough through context clues about what each group is all about and generally what’s going on. I do have lots of questions about the specifics of each group, but I’m hoping that in future episodes (I am only a few episodes in) and seasons they flesh things out a bit more to fill in some of the more mysterious aspects of the show.
And just like a goose, if you step over one you’ll find your nether bits in a very precarious situation.
