Because his point hasn't actually made a point; what he said is far too vague, it needs to be contextualised. Except for superman, he's always boring lol. No seriously the superhero background can be used wisely as it has been done by rocksteady; the arkham series is one I enjoyed a lot, and not for the gameplay, that at times could have been repetitive, but for its narrative and characters, which means I enjoyed it becuase of the source material they took everything from and how they used it, the batman universe. If the same batman universe had been showed to me only through comics, I'd agree I would have found it boring after a while. So I believe could happen for spiderman, since I enjoyed the peter parker characters (himself especially) as much as batman's and it's universe, enjoyable on a movie/video game dimension but not as much on a comic one.
and kalam did make a point, weather is witcher or batman, a whole new world devs developed or a Japanese comic, you'd hardly not play them for being cliché amd unrealistic (all of the above are)
