IMO Twitch and YouTube were great at first because they gave hints and let players see a game before they bought it. But now I think it'll be a hassle. I wonder how many people will actually buy a game if there's 100k viewers watching streams? I can bet a large number actually has the game, but I wonder how many of those are just viewing the stream because the game got amazing scores? I'm sure it'll be fine, but odds are there are people out there gathering as much content possible to just sit there to talk to other people about the game. Which gives no one any money except the service hosting the content. I don't want to watch another person stream Bb because it's in their favor not mine. I can handle a game on my own outside of multiplayer tournaments.
When someone streams its like your friend owning a copy. You can go back there if they want to stream it again. The sole focus is on them. It isn't on the money going to developers. One sixty dollar game feeds ten or more people (even more). The traffic is good, but it has really been about F2P games with the 100k viewers. Bb gets that, but I wonder how many people are just logging back into their F2P game and that's it. There has to be a cost to all that going on. May not be with this game or the next, but sooner or later I think it will happen. You're giving too many people the opportunity to view a game's content to possibly completion. You're gonna offend those people either way. I think the strong hold is given and people aren't developing their own. They rely on other people now.
What I developed from playing games 20+ years ago is not what I'm getting from watching a stream. If anything I see more people catering to the crowd. I paid the money, so I don't need the pampering.
