I think the thing is, games like Minecraft and Plants vs Zombies are not going to be popular forever. I mean, look at Angry Birds.
Now think about Justice League, that has been popular for a long time and even though some kids really don't care about super heroes, many do. Every kid knows who Batman is, but not every kid knows what a Creeper is.
I know what a Creeper is.
I agree what you have to say. Yes, video games are popular now, but there are still kids and teens (I'm one of them) and even adults who loves superheroes in media ranging from movies, video games, and comics. Angry Birds won't ever be as well remembered as Superman, Batman, or Robin. Anyway everyone loves Batman. Call the ride Batman and the Justice League and you know everyone will be there because of Batman.
Plus, WB is suppose to be making a Justice League movie and from what I have been hearing about the Batman/Superman movie coming out soon tons of Justice League members like Wonder Woman and Cyborg are suppose to be appearing. If these movies do well the DC characters will be just as popular as all the Avengers. Anyway tons of people in the video game crowd play superhero games. Hell one of the most popular games recently has been Injustice and I know tons of gamers are excited for the new Batman Arkham game.
Oh, Sally? Niiiice. I'm glad to see after Boomerang they're following up with some more family-oriented rides. It's been a weak area for this park for a while. Justice League would be a great theme for it, too. For once, they would be replacing a ride that doesn't fit the theme of the area with one that actually does. We'll see what they do, but I will be watching this one.
To be fair DC Comics is in charge of publishing all of the Scooby comics. There are even comics with Scooby teaming up with Batman.
