I can understand why you would want to do this, but i wouldn't recommend it. There are WAY too many streamers as it is, market is incredibly over saturated. Don't bother with it, it won't work...
What's the point of "confirming" games you know will get released. Like Nintendo "confirming" a Zelda sequel. "We can't be sure Nintendo is working on a new Zelda game, or if a new Zelda game will ever be released, until they officially confirm it."
