great plot, but more difficult and no DS features
The DS's features are absent, except for a one-time use of a metal detector. Given that previous games had DS features, the lack of it is probably the biggest drawback.
The game can be too difficult and hard to figure out in places, leaving one stuck and with no choice but to cheat online looking at a guide. Others may have found it easier but I couldn't. I don't think I ever cheated so much on a game.
Ardent fans of the series will likely be moderately satisfied. Gamers not familiar with it will likely not think of it so highly. I would still recommend the entire Phoenix Wright series as well as Apollo Justice to anyone.
