Beam taking on twitch? Good luck. Hope it works better for you than Afreeca, hitbox, Azubu or youtube gaming.
With a direct interface from the Xbox? They might have a leg up others didn't.
Using the game bar . . . well, it might have improved since I last tried it. Definitely didn't use to be on par with xsplit and obs.
Wonder if they'll allow 3rd party software for streaming or if they want to really lock it down to MS software.
"The main difference between Twitch and Beam, however, is interaction" That's a game specific thing, not a streaming method/platform thing. And those games exist. Although, not quite that integrated, I believe.
I hope there'll be serious competition to twitch, as that kind of thing tends to drive good service, innovation and whatnot.
