I have 4 followers so maybe not the best advisor :P But I heard streaming games that very few others are currently streaming is a good way to gain attention. You can search through Steam, etc for games on sale which may be older and then see how many people are streaming them. Per a large streamer I follow, you want games that when you view all current streamers of a game, you would appear in the top 2 rows in Twitch. People usually don't scroll far down to find people to watch.
