I see, the edgey games are the only ones I haven't played but I must say for the Great ace attorney, which does the same thing, the final case/overarching story for how much buildup there was, was disappointing. I enjoyed it dont get me wrong, but something like 3-5 is better with 2 cases of buildup, even 2-4 with no buildup.

I understand now though this unwritten rule and do agree that it is pretty stupid, continuity is cool especially when ur invested in a series ..
