It's really difficult to make a really good game on a handheld. There just aren't enough resources/technology to make it possible. However, the amount of good games (70/80+) is more than enough to satisfy your handheld gaming needs.
Plus, reviewers inevitably end up comparing handheld games to console games. Obviously, it doesn't end well for the handhelds.
