And then, you can do a crossover with [@Lord Wraith]. Batman vs Ghost Rider, Justice vs Vengeance!

And THEN, Ghost Rider can team up with X-23, Hulk, and Spider-Man thus giving the game a Fantastic Four!!

AND THEN, Ghost Rider can team with Hellboy and Magik, and y'all can do like an Inferno/Underworld Unleashed type crossover!

Or, ya know, do whateva ya want...
