While distinctly inferior to the other platform versions, this is the best of the series on the PSP.
The load times of the PSP versions were always cryptically horrific, especially in Smackdown! vs. Raw 2006 ; thankfully, this has finally been worked upon in the 2010 version and now they aren't so long, although it would be nice if they could be even shorter. The graphics are good yet the characters are brighter, less realistic and literally rough around the edges. There is no commentary, instead select entrance themes are played throughout the match; the referee's pinfall count is more human-sounding and doesn't hurt the ears as much as in Smackdown! vs. Raw 2009; the crowd cheers while doing a Signature move or Finisher but sometimes cheers at the wrong time and sometimes doesn't cheer at all. The gameplay is still fun as hell, and is even better and more realistic than in the previous versions. There is no HUD anymore, just a momentum bar beneath the player. Their health is judged by their posture. A character whose health is in the red zone will clutch their most injured area and limp if his or her legs are injured.
The new features are great. You can now take different paths in Road to Wrestlemania, there is a Road to Wrestlemania for a created Superstar, combat has been reworked and is better than ever, Royal Rumble matches have a more realistic and intense way of eliminating opponents, and best of all: you can create stories.
If you want a wrestling game for the PSP, this is the best choice.
