Overall, Miami Law is a serviceable graphic adventure title. It's not the best one on the system, but it's not without its merits. The idea behind it is intriguing, and the separate storylines actually help to further provide something unique, and it's refreshing to play something that's quite straightforward. However, the storyline isn't all that fascinating, some of the mini-games don't work as well as they should, the game can be beaten and forgotten about in a ridiculously small about of time, and there just isn't much incentive to go back for another stab at the game.
Visually, the game works well enough, as does the soundtrack. If you really must go for an adventure game, go pick up any of Cing's games (Trace Memory/Another Code or Hotel Dusk: Room 215) or any of Capcom's Ace Attorney games
