I haven't actually completed the game yet, so this isn't a review. Instead it's just some rambling about the game.
The first comment has to be that Phoenix Wright: Ace Attorney: Trials and Tribulations is just like any other Phoenix Wright game that's been released on the DS. Astounding, I know.
But that's just it, it is simply more of the same. It's five new cases, using the same gameplay as the previous game without the special DS-specific case that the first Phoenix Wright game offered.
