Yes, but for those who don't watch anime or play anime games, it can be great to get summaries so you have context for some conversations. Like, if a friend of mine watches a TV show or plays a game when I don't, if I have no interest in watching or playing, I have no context. Maybe I want to support my friends interest without putting in the same hours so it's nice to be able to get a summary or just the important parts so I know what my friend is talking about and can at least converse with them on the basics. (Though I do believe such videos should have giant spoiler warnings)
