Neat, HolofightZ has been going for over 18 months now, 33 streams with matches and a TON of promos and intros. They're a loose collective of video editors and modders and some of their channels are amazing. Some of them also do other agencies like VShojo but i don't think they've set up a tournament yet.
I'm not sure how much of HoloFightZ is just AI v AI and how much is scripted? I read that Eggroll is running AI vs AI but either way they remind me of when i had my Dreamcast setup in the corner of the office and had fighting game AI battles going on behind me so when i needed to space out and think on a problem i'd just spin my chair and watch some stupidity going down for a bit. Ha.
The creativity of these teams making these VTuber wrestling models, videos and whatever is amazing though.
It'll be great to see Niji do some custom chars and wrestle matches/tourneys too. Ya buncha marks.
