I bought this game and finished it a few days ago to satisfy my need for a new Ace Attorney and I have some thoughts.
Pros: Love, love, LOVE the Argument system and hope it stays if a sequel is made. When Last Stand kicks in during Court and an Argument start, it's like doing Pursuit in manual mode so to speak. Instead of Phoenix/Apollo/Naruhodo on autopilot with maybe one easy present, this game has you presenting evidence rapidly to shut down any possible argument the killer makes and really invokes that "You are not getting away from me" feeling from the player. The actual cases are pretty good all around, with maybe the tutorial case being the worst of the five.
Cons: Case 5 wasn't able to finish as planned and thus had to resort to a Monty Python and the Holy Grail-esque ending (Budget ran out so just end things abruptly). The Court Record actually ended up being my #1 complaint overall as nearly all the cases had some bloat to the Court Record and completely useless pieces of evidence. Only the first case had crime scene photos and detailed layouts of rooms whereas the rest was mostly just portraits with the word "Testimony" or "Compendium" written on the bottom right corner. You did get maps of the building the crime took place in for cases 2 to 5 but not the kind you got in case 1.
Compared to other Ace Attorneys: Solidly mid tier. Doesn't hit the highs that Ace Attorney hits but doesn't hit the lows that Ace Attorney hits either. AAI2 > 3 > 6 > 1 > TC > 2 > 5 > AAI1 > 4 feels right.
