Phoenix Wright proves to be a thoroughly enjoyable experience through the many hours you'll be playing it.
I won't lay too much into the background story but basicaly you're an upcoming barrister fighting for your clients in court. That's basically the premise of the game. However, I'd say only 25% of the game is actually played in the court, whereas the other 75% involves you going round different locations finding out clues for yourself; which is probably really the only downside because I don't know of too many barristers who get their hands dirty and go to the extremes that Phoenix Wright does.
Anyway, the gameplay plots out as you taking upon a case, going to different scenes back and forth, back and forth getting clues and evidence ready to present to the court. The good thing is that the game will let you know once you've down everything and it will allow you to go to the next stage of the game; i.e. in the court. As I mentioned you will be going back and forth alot through screens again and again trying to find evidence that you might have missed out and this is the only real downside to the game. However, you'll soon get used to it and you'll have to learn to live with it to experience the much better bits of the game i.e. in court...
The court side of the game is the most enjoyable thing in my opinion (Considering I want to become a barrister when I'm older, anyway....)
In court you basically have to put your wits to the test and from this point on it's a really complex, intelligent side to the game where you have to find flaws in the witness' statements and anything that the opposition might say. Through these ways, presenting evidence, objecting, finding flaws in testimony's, you'll solve the case and ultimately you win.
So that's the gameplay side of things and that's what really makes the game stand out. The story is good, the cases are really varied and detailed and the overall story to the world that you're in unfolds before you and you get some nice little things towarsd the end of the game that make the end-game content really worth getting there for. Anyway, it's a great game that I would recommend to anyone with some patience. If you don't have patience and really cannot go through screen after screen by hitting a "move" button then this isn't the game for you, sorry.
