Streaming is super easy nowadays, the functionality to stream to twitch is built into PS4, and maybe PS5, can’t say as I don’t have one.
For recording/streaming PC games, OBS Studio is free and open source.
You can also stream/screen share on discord on PC, I assume you can do it on consoles, as well.
Steam also has game recording, now.
Since this would be just a small community thing, you don’t need a fancy microphone or really any voice recording, at all. So that’s the easy part.
I like the idea of using Fire Pro, but IIRC, it’s possible to edit the stats of any wrestler in WWE2K, even the “vanilla” ones. I used to make every wrestler a perfect 100 for my nephews so they could pick their favorites without worrying about arbitrary numbers. Granted, it’s a universal change, so if you’re also playing a career or fantasy booking mode, that will also be effected.
The hard part is getting a group together to actually make it happen. Schedules and jobs and all that.
Mina turns on a lot of people.
Oh, wait, not what you meant…
