From first play, I would rate the game a 9. But, sorry to say, as I played more, the game became disappointing.
It is a blast and very fun to play in the star wars world. The use of the heroes for only a limited time is a good feature, as the hero is very effective in combat. Most of the specialized units are fun to play, but only on the appropriate map.
I did not have any problem with the controls, I used the advanced settings, but did take a but to get used to, especially when the lock on moves your viewing angle for you in close combat! Keep trying, you'll get the hang of it.
I would have to say my favorite map is either the Hoth map or Kashyyyk. Either map had the best variety of game play: all unit types are effective on these maps; ground vehicles, many stationary gun turrets, and on Hoth, snow speeders and AT-ATs! Very fun to play, by far the best of the game.
What I desired the most to play was the space combat and strategic portions of the game. It started out fun, but, this is where fell down. Likely, a casualty of porting to PSP.
First off, the conquest battles in space are not fun. If you are to win, you must be in the bomber (Y-wing, or Tie Bomber) to effectively destroy the enemy sub-systems and gain points. Your AI is not effective enough to do it. Strangely, the enemy's AI damages your ships effectively and quickly! That's why you can't afford playing around in the attack ships, destroy those sub-systems and you'll win easily. Another disappointment is that the equivalent space units all play the same. And, the space marines are a total waste.
The strategic portion, starts fun, but gets tiresome. A big bug to me seemed that the AI never ran out of points to build new fleets, no matter how many it lost or how few planets it controlled. None of the mode variations made much difference.
Finally, your character profile is detailed, but too bad you can only seem to view the statistics after a battle!
This game will fulfill your need for Battlefront on the go but it's missing a few controls that would make it more fun, but it's not the games fault it's the PSP that is at fault. Overall it's a decent game but because the controls are awkward it reduces its rating.
