This is very obviously a language barrier issue at play here that people are ignoring just to take what he said at face value. There’s zero chance that what he meant was the game was _too good_ and that as a result he wanted to _make it worse_. He almost certainly meant something more along the lines of the plot, or something to do with the game mechanics were too streamlined, or otherwise not challenging enough in some way.
