You can get fun from G-Force for PSP.
The graphics of G-Force is not bad and fit for PSP. The story is good, because it is adapted for film. As the captain of G-Force, you're misled by the final boss. Of course, you'll win at last.
As platform jumping game, G-Force's level design is ingenious. You must try to find the way you can get through. With jetpack the guinea pigs get more mobility. In G-Force, you just only fight against various enemies, because these is no boss. Actually, Enemies is our household appliances. You cannot underestimate them, you must beat them in unique ways. Nevertheless, the combat is too simple and invariable.
Another weak point of G-Force is that the sound effect is poor. But the worst thing is the hacking minigame. At first, I appreciate it, but after a while, I find that it crops up too often which slows down the game tempo and break up the story.
G-Force for PSP, I believe that, is one of the best adapted games.
