For what it's worth, I personally liked Ghost Trick better than most Ace Attorney games. I can't quite say I liked it better than AA1 or AAI, but it's definitely up there. It's really short though, I beat it in one sitting. (which is something I very rarely do.) I'm talking 6 hours short.
And everyone should see the panic dance.
EDIT: Also, Lynne is Maya DONE RIGHT. I hated Maya, but Lynne is one of my favorites from that game. Which is saying something, because I actually think Ghost Trick has far better characters. Cabanela is a beast.
EDIT2: Spoiler alert: The main character dies.
