I actually bought this game to see what all the fuss was about. The first part of the game is kind of fun, a really basic Tokimeki Memorial, but once you get to the romance part it requires too much time. It runs on real-time, so you have to make dates and remember them. Since it's supposed to be realistic, you can only schedule dates during reasonable hours (aka, at times where you would normally be doing other shit) and you're expected to play the game on a daily basis, writing mundane emails and talking with her on the phone. After awhile I guess it goes further and requires more time, bloody hell. I stopped playing the game after I realized what a waste of time it was (and my girl got pissed at me because I arrived an hour late for our "date" and stood her up). Heh, I should probably put it in again to see what kind of nasty messages she's sent me in the few months we've been apart. With all of the effort you have to put into the stupid game, you might as well just get a real girlfriend.
The game also has a feature where you can travel to different prefectures in Japan and get special unique items related to that prefecture by going to a DS Download station. I wonder if anyone has been crazy enough to collect them all.
