Tedium is a cheap way to make games longer. Maybe the guy in this article takes advantage of that. Independently, there are players that enjoy repeating difficult sequences, to an extent, while they gear up to do the next part right. Punishing style of games existing isn't a bad thing. What the guy in TFA is saying is unreasonable on its face. He insists that MORE players enjoy the type of game he is making. He's complaining that other people making their games better is making his look worse.
