It’s a constant Circle though, they stream what’s considered popular but because they stream it more people play it which causes it to be even more popular
Look at lethal company as a prime example of that, if streamers never took that game it never would have gotten anywhere near the publicity that it did
specific games like Minecraft I think it’s nessicary, other games such as call of duty which insists on having one launcher manage all game installs I don’t think is.
Imagine trying to handle all the different minecraft installs from the main screen, you would need to launch Java, load a Minecraft game, load a profile, close the game, open the game with the new profile settings and then hope it launches. This setup is very helpful, but I agree most games it is not helpful at all
