Shrug, that’s fine tbh. I personally disagree with you. This feels like it’s trying to reach teens and young adults with a lot of the more popular and trendy topics but you are free to have your own opinion. Agree to disagree.
I mean most gen z are already adults just 6 more years and every gen z person will be 18+ in the end of 2030
But obviously you most likely are more around younger communities if you are younger so it's both from a different perspective but the slangs and vtuber stuff is not that uncommon at all in adults you probably notice it more once you are older.
Again not saying it's not reaching a younger audience but millennials are not some ancient folks who don't enjoy slangs or watch certain vtubers lol.
I was also again talking about her community not this specific game's audience
