Types of Omegaverses
Traditional - rigid social norms and hierarchies (ex: you can't do that you're an omega!), scents, animalistic heats/ruts, packs, war, dynamic > gender, mating, traditional gender roles are imposed (even if your characters actively fight against them), majority polyamory or familial based packs. Knotting = mating bond, mating bites can be present.
Contemporary - semi-flexible but present social /dynamic hierarchies (They are an alpha, it's respectful to listen to what they have to say), dating and courtship either anywhere between traditional and modern, polyamory common, dynamic is slightly more important than gender in society, familial/harem/community-based packs, fantastical heats/ruts/and mating, knotting and mating are not the same thing, mating bites, soulmates/soul marks.
Modern-dynamic hierarchy used to be a thing but is no longer the way society is structured, some dynamic and gender-based social norms (ex. I can't believe that alpha is a kindergarten teacher, i wonder what their parents think!), modern/nearly modern dating and courtship, traditional gender roles in the background, dynamic and gender are equally important in society, found family packs, polyamory uncommon, realistic heats/ruts (no rut rage, no wildly uncontrollable urges that last for days, no fountains of slick, etc.. these are just quirky biological processes, the increased mating drive does not become "fantastical"), mating bond = emotional commitment.
Post-Modern - the coexistence and explicit mention of multiple countries, multiple languages, multiple cultures, and customs that inform feelings towards dynamics. Mating, packs, and social hierarchies, neither dynamic nor gender is the focus of the characters or the plot, heats/ruts more biological than sexual, present-futuristic time period.
