I also think he just sold because of all the upcoming issues, and the apparent ‘hate’ he received for it.
But, i also think that he has had his time with his Minecraft ‘baby’, and made more money with it that one could ever imagine, and pretty
much had to devote himself to this game, and nothing else. (Without making some kind of compromise between)
I guess the fame and the resulting ‘responsibility’, to keep working on it, to continue and continue, for the fans etc. broke him.
I’d say that if he had sold millions of copies, without becoming a star, he would have continued longer.
If you asked me this questions a few years ago, i’d tell you that i would never everr sell, since ‘it’s my baby’, but nowadays i would want to walk away from a
project and do something else.
The worst thing about it is, IMHO, that Microsoft bought it.
But Minecraft will always stay what the fans make of it, nothing else, and strongly suppose that Microsoft won’t (and also will not be stupid enough), to try and change it.
