For those of you guys that never played the game because it never got an official translation...please, do yourself a favor and play it. Especially if you are a huge fan of the original series.
What makes this game stands out above every other one in the series(to me at least) is that every single one of its cases are interconnected. I don't mean this in the sense the previous Investigations game had cases be vaguely connected to each other, I mean that characters in one case are important in the other and character development extends across cases.
Unlike every other game in the series, the package of 5 cases genuinely feels like a single large story with no/little filler in between. Every case is fantastic, villains are entertaining and the annoying comedy relief character was one of my favorite characters in the series by the end of the game.
One thing I don't like about post Trials & Tribulations PW is that the fact that the spotlight is shared between Phoenix/Apollo/Athena and it results in a very unfocused game. Here, the game is laser focused on Edgeworth and that combined with the very tight story make for some very, very entertaining hours.
This is not to say that side characters don't get developed(they certainly do) but the fact that the game never lets you forget that this is Edgeworth's show from start to finish makes the game tell the story it wants in a much more effective way than Apollo Justice, Dual Destinies or GS6.
(Major spoilers about this game's ending, just because I want to gush about one particular scene
Man, I seriously didn't expect to like Debeste/Yumihiko nearly as much as I did. His development from joke to "I know I'm a joke but I want to grow up now" was in my opinion the best done character evolution in the series by far. Always love the scene when he's standing in court against his dad.
TL;DR: If you like Ace Attorney, go play this game. Man I love this game so much.
