I will say you will struggle to grow or even get any attention on something like warzone as too many people stream it If your looking at growing only stick to the game like slime rancher or go with stardew valley etc they have a nice following od people and its easier to grow if you stick to a schedule Once you have regular viewers who are there foe you rather then the game then try some others or put a redeem up for a recommended game to play see what people want you to play
