How do you collaborate from a distance?

I've been talking with a few people who just started like us and we've been thinking about doing some collaboration videos together, I'm just curious what's the best way to go about this. Posting here because this is about the technical side of doing a collab and not a request for collabs Do we play the game together online, use one capture, and have them send us the audio (or we send it to them if they're the ones uploading)? I think it'd be a lot of fun to start doing this with multiple channels and a cool way to get our small channels out to other audiences that may not come across us otherwise.

Also, if you're interested in doing this with us, let me know!
