And yet you casually quantify talent as being about making a
fun game. There are so many flaws in this line of thinking.
At the top is the idea that if you make a game fun enough it will take off like Minecraft, but virality is not simply a product of fun, there are so many intangibles that go into blockbuster successes, and the people who get really good at wrangling those elements and distilling out a formula are not renowned for their talent (eg. Hollywood blockbusters).
But unpacking further, talent is something that needs to be developed. Natural talent is nothing without practice upon practice. Talent in some area requires years of practice that laymen will never really understand or appreciate. We can all talk casually about various kinds of talent, in programming, in art, in game design, in music, etc, but any kind of serious discussion needs to touch on the nuances of the specific work they are doing. Claiming Nickelback is more talented than Arcade Fire because they've sold more albums is a sure way to kill a conversation about music.
