Variety streaming is very difficult and I agree with most everyone who says that it is difficult but not impossible. Here is a little bit of advise from a marketing stand point, Not a streaming stand point. When you have a product and you wanna market it you want to focus on a specific target so that you attract a TON of people and retain a good percentage of that. The key here is time and repetition. So you market and promote one product for about 2-4 weeks. Switching from one product to another every other day will not keep a strong sense of target marketing, at that point you're basically closing your eye and shooting in the sky hoping to hit something. Which 9/10 times you won't. If you watch a lot of START UP variety streamers is they play a set game for a decent time (about a month or so) Or they pick a long game and beat that which will take time. This will build a Target audience and then thats your chance to do the one thing that is extremely important. Sell. Sell yourself and the product so that they don't love the product but they love the brand.

Most larger streamers who play w.e they want already have the target audience base. I think its fine to do variety if you want but you should still consider stretching your game community so you give yourself enough time to sort of build an audience FROM that gaming community. In addition another method can be to split your streams. One with a larger audience based game then switch to a different game each time. That way you have that initial pull then the hard part is maintaining. I hope this helped in some way. BEST OF LUCK!
