the genre has nothing to do with the hype level
The Walking Dead season 1 popularity blew up even though the audience for that genre was almost non existent
before and after Spider-man came out, people talk about it everywhere and praise it like it's an amazing ground breaking game like Witcher 3 or Zelda: BOTW even though Spider-man is just a generic open world game with repetitive quest, main quests that are fetch quests, boring and repetitive melee combat and tons of collectibles and Ubisoft towers, every generic open world thing is in the game, and yet it's popularity exploded, don't tell me because Spider man is one of the most popular characters, The amazing spider man 2 video game sucked balls and had zero hype, i know it was a bad game, so popularity is not based on character, we all know why the new Spider man, despite being a mediocre game, yet received high praise and sold millions in days, the answer begins with S and ends with Y
Forza Horizon is top of it's genre, no competition at all, it's like Forza horizon is Witcher 3 and all the other racing games are Dragon Age 2, and yet it's not that popular, you don't see anyone excited about it in social media or among friends and colleagues, it's like it doesn't exist
