I have played and finished the first three Professor Layton. I'm on the fourth one right now but will be getting the 3DS version soon.
And in the Ace Attorney Series, I finished the first three Phoenix Wright titles (GREAT games!), but I'm only now going through the Apollo Justice title. I've also played the Ace Attorney Investigations title starring Miles Edgeworth.
The Ace Attorney titles have Aweeeesome localization!
