Honestly, I don't think DC can produce a video game that will please absolutely every DC fan out there. Lots of people were happy that the Batman: Arkham series would supposedly end with Arkham Knight because they wanted DC to shine the spotlight on other characters, like Superman, and believed that DC focused too much on Batman, but the usual counterargument to that is that DC makes Batman games because Batman is a huge fan-favorite. Asking DC not to make Batman content would be like asking Nintendo not to make Mario content.
Seriously, what can you do?
