Rewatch PvP fights and post in chat

I want to rewatch PvP fights and show them to my guild in chat.

Are you referring to your own or someone else’s fights?
If it’s your battle, record it utilizing a variety of methods while you’re playing.
If you’re referring to someone else’s then watch many YouTubers that record their fights or follow someone who plays games on steam.

My own battles , like a won a close one to a high lv player and I want to show it to my guild members …

OK? Go ahead.

what platform?
pc: many options. i use nvidias software, but google will be your friend there
xbox/playstation: i believe both have in built options, but a capture card to pc and obs
switch: capture device and obs
switch lite: external camera and point at screen.

I’m actually in favor of a replay system - because external tools to record gameplay are rather awkward, price-wise, and I’m of belief that free-to-play services should seek to empower the users that choose to play for free, yet still choose to be a strong advocate for the game in question.
I’ve had Citadel Fights that I would love to show off despite being severely undergeared for it, but I now have no way to recreate the fight. Having snapshots of the random seed before each move (as well as starting stats for both sides at the start of the replay), and then listing co-ordinate, and direction, I think that would succeed in creating each replay.
I would see concerns for space, but unless a fight extends well past a thousand turns, you could probably store the data as a text file, and still be storing ultimately chump change for data.
Kinda up to the devs, but I’d love a way to support GoW without means of external tools or software (beyond the TV and controller, but that’s pedantics).
