Seriously, it never fails that Gamespot would rate such a fine game so low. I'm having a blast with it, I show it off at work at EB Games (which, sadly, I resigned tonight because I'm graduating from UT to take on a better opportunity) and everyone oos and ahs over it, and in classes on campus at Texas, same thing. The game is a lot deeper than it looks.
I really thought this was the one game I'd see Gamespot give at least, you know, a 7.0 (respecting Gamespot's strict scoring system), and they didn't ever give that.
It's also odd how low the Gamespot score deviates from the average press score (which, last I checked was around an 8.0).
Regardless, if you own a DS, you should definitely check this out. It's worth the $30.
