Double standards and reviewer quirks make Gamespot's offiial review inaccurate.
Take Brothers in Arms DS, for instance. It's one of the most impressive games on its platform. It's gameplay mechanics are lifter pretty much straight from Gears of War, no less, and it has hands down the best graphics ever seen on the portable. It's also built in 10 minute sized missions perfect for portable play, has a multiplayer mode and, all in all, pushes every boundary of DS gaming.
GS has focused on its problems, though. The camera is far from perfect, and so is hit detection. It IS possible to get stuck under a car or to make the camera go crazy in a tight corner. Sure, that happens. Restarting when the first issue happens is not that bothersome, given the game's extensive checkpoint system and the camera... well, to be honest it's not that bad if you compare it with cameras in other 3D games of the N64 or even the DS itself.
Then there's the AI. It's certainly not there. Every enemy will do what it's programmed to do and just that: if they're told to charge your tank and try to drop a grenade inside, that's exactly what they'll do. This issue is very much solved with great level design. The situations in the game are such that you can be sure if some enemy is trying to drop a grenade in your tank, or to snipe you, or to provide cover fire for their partners, then that's the intelligent thing to do. They can't adapt, but unless you find a way to play the level in a completely unexpected way, you won't notice.
And then there's the control system, which I'm guessing is part of why GS's grade is so low... But it shouldn't. The reviewer complains of being unable to do several thigns at once quickly with the interface. I can only say he's punishing the game for not being able to play it properly. It doesn't take more time to reload while you walk than it'd take in a PC FPS... or real life, for that matter. Everything is available to you with just a tap of the stylus and everything can be done while you have the character moving with the D-Pad. The reviewer complains about pain in the wrist while playing, which I admit will happen if you play for long (like, I don't know, if you're trying to finish the game in order to review it), but it's an issue of the DS as a system. It happens also in Metroid Prime Hunters (in fact, it's much worse in that game due to more double tapping being required, which will force you to hold the console tighter). Metroid, however, got an 8.6. I'm wondering if other stylus only action games like Phantom Hourglass or Ninja Gaiden will receive a similar impact in their scores.
Overall, I suggest you actually read GS's review and disregard the score. Brothers in Arms is a fun game, packed with options and it looks and plays surprisingly well. If you're looking for a mature action game or just a shooter for your DS, this is it. You won't be disappointed.
