Yes it is a new phase of gaming.
We need to keep in mind the streaming world has been around for about 10 years now.
I am sure some publishers take it in mind. But the biggest player in streaming is Amazon. They purchased Twitch awhile back and use it to funnel sales to their ecommece platform.
To me the biggest “newest” winner of gaming And streaming is dungeons and dragons. Sales have skyrocketed from streaming of game sessions.
Off to work.
