Jeez I can't wait for a good X-Men game to show its face. Button mashers are fun once in a while, but with the deep lore that you can draw from a famous comic book, I am sure that something better can be done.
Look at how well Rocksteady made the Batman games. I am sure that something can be picked up from that.
Also, in the broader perspective, it is not just X-Men. Superhero games in general are failing badly. Spider-Man had one or two good games, Hulk has none, Iron Man has none, Green Lantern wasn't as good as expected...surely someone can pick up these titles and create some masterpieces.
