After the series went 3D I wasn't interested anymore. They destroyed some of the best art I've ever seen in a game!! So sad. But hey, I'm always interested in seeing more amazing Layton-style animation, regardless. :)
I own, played, and love* all the games except the last one. Amy and I played through them all together but on the last one I just got tired of huddling around the 3DS trying to play a handheld game co-op. I've been holding out for the ability to play 3DS games on the TV. I would FLIP OUT (in a good way) if the NX could play 3DS games on the the big screen.
So, yes, despite that snag, I'm still super psyched to get this game!!!!! And, given the fact that Hershel's story has already had plenty of meat to it, I think it's fine introducing a new main character into that universe. I hope there are cameos from all the favorite characters in the past games!
