@Janet oh, it's by an artist.
I thought it was an avi with interchangeable modular gear. I'm not sure how I feel about that. Which metaverse engine is this catering to? You mentioned FB before but I believe they'll do everything in-house to avoid copyright lawsuits and other legal quagmire. I know Shiba is creating their own metaverse but I've only got a cursory understanding of it.
I've kinda pictured only one company will really prevail in this, coming out like "Summer Wars" or Ready Player 1
