6.5K Subs on Minecraft Content Is Branching Out Worth the Risk or a Growth Killer

I make gaming videos mainly Minecraft Lets Plays and have around 120 videos and 6500 subscribers. Ive not branched out playing other games yet as I am scared to disrupt my channels growth. Has anyone had struggle branching out? Was it worth the risk of subs not watching and it not being picked up by youtube? Should I continue to stick to the one game to grow on youtube or will my audience just adapt? Not sure if just overthinking
