@All_bonesJones Depending on how many items there are to cover, and how much you have to talk about, you should consider doing multiple videos. For example, one to cover the real history of the shields, one for swords, etc.
I haven't played Elden Ring, and I'm no historical weapon/armor enthusiast, so I don't know jack shit about what you'd cover here, so ultimately you'll have be the judge on how to structure your video(s). But if it goes longer than 15-20 minutes, it might be better to stretch across multiple videos.
Definitely a topic worth covering though. I don't really see many videos covering the real life inspiration for video game weapons/armor. Shadiversity might have some of that, but he focuses mainly on how the weapons would handle, and any historical comparisons are secondary.
"How realistic are Elden Ring's [category]?" could make a fun video series. That's actually a really good premise for getting people to click instead of "here are the references used"
