The third case was bad enough that it drops it down quite a bit but aside from that the other cases are pretty good. I'd really recommend just skipping through Turnabout Big Top. The final case is one of the best in the series and could arguably be considered the best.

The magtama and profile systems made the game a little more difficult and confusing in some areas, but a lot of AA games are like that.

I also appreciate Franziska Von Karma for how over the top she is. She's like a mary sue but it's fantastic .
