To clarify a common point of confusion: Mortal Kombat vs. DC Universe
Pros: You play the exact, unaltered console version using the PSP as a controller. You get the full story mode, including the infamous "Rage" mechanic and the Teen-rated Fatalities (no decapitations, but lots of particle effects). Cons: Input lag is noticeable. Playing a fast-paced fighter like MKvsDCU requires precision. For casual play through the story or "Kombo Challenges," it works fine. For competitive play, it is not ideal.
Let’s get one thing straight: Mortal Kombat vs. DC Universe on the PlayStation Portable is not the "best" fighting game on the system. That crown belongs to Tekken: Dark Resurrection or Street Fighter Alpha 3 Max. But "top"? In terms of pure, shameless, portable arcade chaos? Yes.
The absolute best native Mortal Kombat game on PSP, featuring the full roster plus exclusive characters like Shao Kahn and Goro.
