Mortal Kombat has had a rough history of ports and Street Fighter has had a rough history with games like SF 2010 and their first titles. But they tend to have a solid grasp of how to make a good fighting game, which can be hard to say with old Mortal Kombat like the Game Boy ports, Sub-Zero for the N64, and then add a bunch of DLC for their recent additions making the game series even less appetizing.
