I wasn't aware that minecraft was a purely cloud based game, to do this you'd have to root your chromebook, get access to the linux kernel at it's base and basically turn it into something that isn't a chromebook, you'd be better off buying something else.
There is an app for the game and there is no lag you dont need to root anything and with chrome book you cant install anything it is all cloud based . the processor rock its the fastest computer i have ever had or worked on and i have worked on apples, simple dos ,and more. if you want to make sure you can go to the chrome book store and check out all the apps.
I have no idea. I am not a gamer. But I love my chromebook. I read the reviews.. ppl couldn't stream netflix... maybe they fixed that glitch, because I can perfectly fine. Youtube is great. Not perfect, but almost.. It is fine. Although you have to be logged in to stream netflix. You can't be logged in as a guest. I love mine.
