DC Comics - There are exceptions of course

300 is the perfect choice to represent the movies because it was directed by Zack Snyder, and I can only assume that wasn't intentional.

I kinda want them to try another Mortal Kombat vs. DC Universe game, or I guess it would now be called "Mortal Kombat vs. Injustice". The Injustice games are pretty brutal despite the T rating, and the Mortal Kombat guest characters show that said characters can work well-enough in a T-rated game, so they could try another crossover game and avoid the pitfalls of the first one.
