Hahahaha, I bet all of you didn't say this so I could. Anyway shion...

The Ace Attorney Trilogy, in chronological order.

In fact, if you do indeed start playing Ace Attorney please play in this order to get full satisfaction of the games' story.
Phoenix Wright: Ace Attorney
Ace Attorney: Justice for All
Ace Attorney: Trials and Tribulations
Apollo Justice: Ace Attorney

I'm sure they'll be hard to find though, so good luck with that! Just my recommendation!
