Mortal Kombat vs. DC Universe is fun and a solid entry into the franchise, but I doubt many folks will find it entertaining past a rental. Casual players will punch through the storyline before burning out after getting stumped by one or two Kombo Challenges, while Mortal Kombat fans will have trouble accepting the toned down Fatalities and somewhat slower gameplay. In short, this game's fun, but its legs probably can't carry it beyond the whole "Wow, Batman's fighting Superman" first impression.
