DC has been featured heavily in video games over the years — there have been video games based on DC superheroes for almost as long as video games have existed. As time pressed on, DC spread into the different genres of games, and it was only a matter of time before DC's best crime fighters made their way into the intense and technical world of fighting games. The first major attempt at creating a DC fighting game was, infamously, Midway's Mortal Kombat vs. DC Universe. While it was a decently competent fighting game, it was largely met with mediocre reviews and many disappointed fans.
