Not quite. I think one of the earlier game that make use of all the DS feature - even the closing DS to press something over - is Tracy Memory. that is an adventure game with alot of puzzle like this. kind of a little simple but i think they make that game on purpose to have fun with the new DS features. which is pretty creative at that time.
I agree that it is very cool that this game uses all features seemingly possible. I would have to disagree there Jacoblam, because there is a trade mode with 802.11 on this game. You have to find the passage on the main Island and talk with the guy that plays his guitar. BTW Is there many of you guys still playing this game? I'm not makin fun, just wondering. Also if any of yous guys need help let me know
