No, he's made it better. TDK is broadly considered the greatest superhero movie ever made: it's got the highest Rotten Tomatoes score, the highest IMDB score, and the most oscars.
Hate to be that guy, but:
Arkham Asylum sold over 7 million copies and Arkham City:
Over an addition 8 million. Then there are the special editions of the games for which there aren't any sales figures.
Also, there's a disparity in media. One is home media, and one is not. For example, a lot of people go and see films more than once, so that would need to be factored in for sales, whereas a game only needs to be bought once, then it can be replayed as many times as you want, it can be lent out, sold and resold, whereas film tickets can't.
A better example is when home media sales are compared to home media sales, in which Arkham suddenly holds up much, much better. The Arkham franchise all in all contains a little over 16 million sales. Now, The Dark Knight alone beats that with almost 18 million, but The Dark Knight Rises fares much worse, with only just scraping over 5 million sales. So combined TDK/R have 23 million sales compared to Arkham's 16, but that then means Arkham makes up over 75% of that same audience.
The films reach a wider one-time audience, but but in terms of pop culture conciousness, there isn't massive disparity in the long term impact between series. I'd also like to add Batman '89 outsold The Dark Knight Rises in ticket sales. But cross-media comparisons never work.
