As a sequel to my previous "What if video games no longer existed" thread, I had dared propose something an even gloomier and potentially more grim and apocalyptic hypothetical scenario to the whole world. Beware, this thread may make you lose your entire sanity and give you lovecraftian-levels of stupefying insanity and madness.
Anyways...
1) What if Japanese Anime/Manga never became popular on a world-wide scale?
2) What if Japanese Anime/Manga never existed or became popular at all?
3) What if Japanese Anime/Manga stopped existing tomorrow?
Bonus: What would you do if Anime/Manga from Japan (or any nearby parts of East Asia, if I wanted to be a dick and make the scenario trickier) stopped existing? What similar things would you replace or substitute it? What would you turn to now? What happens to the world (no comments like "the world becomes a better place with all weeaboos are gone for good")?
