I don't agree. Video games can be a lot more than just "fun". This is an outdated approach and the simplification of this statement is insulting to games that actively try to be more than just "fun".
And why would they have to be fun for everyone? Why is catering only to a specific audience bad?
Fun means enjoyment, why exactly are you playing any games if you arent enjoying them? for what reason would their be a point to them? to not enjoy them? to not have fun?
What is ironic is that this user's 2015 goty is 100% a product of that outdated and archaic philosophy. Go figure
