Commercial show matches.

1) The idea is interesting, but it has several serious flaws. 1.1 - There was an introduction of a paid, high-quality channel for streams; some people bought it, but the quality of the free one seems to be the same now. 1.2 - If you implement a system like most other games, you need to rework part of the Heroes' mechanics. The observer should be in the game because re-streaming has several significant drawbacks (delay, desynchronization of the two streams, quality). 1.3 - Do all the top players have computers that can stream in good quality? It's unlikely that a re-stream will be that good. 1.4 - Many streamers earn money from advertising on these streams. Try to explore this direction (donations + bonus from the stream (contract with Twitch, etc.) and something else), and all of this could potentially generate a decent amount of money. 2) As mentioned above, everything comes down to the duration. 3) The time from 8 PM to 12 AM seems to be the most optimal. 4) I'm not a great player, but I can be a commentator, as I have a good internet connection and a good computer. 5) There are many streaming programs now, and they are quite easy to set up. For example, Open Broadcaster Software. Additional note: There's a slightly different idea. What if the commentator explains not the game as it's happening, but a recording? Then you can properly edit everything, figure out the main points, and possibly include comments from the players themselves – a complete analysis of the game. This would be both interesting and educational. In other words, make it not just a game with commentary, but a real show.
