Excerpt: Foto Frenzy takes the I Spy concept of game play and tweaks it in some interesting ways. First off let me say, this is the most difficult “find the differences in photos” video game I have ever played. I had to bring my own levels of playing to a whole new level. I also did not realize (at first) that there are so many hints per series. Even with those, this is one tough Nintendo DS video game. Well at least it was for me.
