The DS version of The Force Unleashed tries to cram all of the light-saber-rage from the consoles into a handheld package. You'll be disappointed if you directly compare the two. I recently tried a late version of the DS game, and I didn't think enough of the system's strengths and weaknesses affected the design. The DS game gives a 3D perspective of the action on the top screen with adequate visuals, but the chunky graphics steal some of the excitement. And since the camera can't be repositioned, you'll be regularly attacked by people just off-screen. Worse, player attacks are issued by tapping on icons, causing hunting-and-pecking through battles.
Since The Force Unleashed is about going nuts with explosive superpowers, that sense of excitement got lost by scaling everything down to fit the DS. A wireless, four-player, local battle mode might make it a fun game to play with friends, but I wasn't able to test that feature. I hope the final game will grow on me after its September 16 release. But the time I had with this portable edition left me cautious.
