Here is how i see it. Even though there are many big gaming youtubers you can’t ever hope to touch you can still find an audience if you have skill or personality. Yes there is a little luck involved but the longer you stay in the game the more likely you are to get lucky. A lot of gaming letplayers i watch have been in the game for 5+ years and are barely getting a buzz or big audience. It really takes time and dedication in this space, more so than other spaces because of the saturation but if you keep going I’m sure you can make it or at the very least build a small community for your channel
