I've just finished this too and pretty much avoided this thread while playing (and anything else on the game) so I'm just reading these fresh now. For me, I really enjoyed playing it. I would agree with Angela's ranking (behind 3 and 1, ahead of 2).
As I'm Negative Nelly, or whatever it was, I'll get my big negatives out of the way first. Given that this was the first AA game designed for the DS, the first new game since maybe 2004, I was disappointed to see almost no progression. In fact, I'm with you Angela on the Profile presenting and Psyche-Locks so I actually felt this game a step backwards. And it felt plain lazy to me that responses to presenting stuff were so limited. The Investigation parts always felt weak to me in the PW games. In my opinion, the game really needed something like the Psyche-Locks and a lot of good responses to keep those interesting.
I found the investigation parts of Episode 3 a real chore and painfully dull.
There was the Perceive system, which was nice but it's not the trial parts that needed that extra attention and it was so limited in use it didn't really feel like an actual addition.
While the game got a lick of paint and some of the animations were stunning (Klavier's slam and guitar in particular), I would liked to have seen this go even further. There's no doubting the ability of their artists and it would have been just lovely to have put a bit more actual animation in there. On that though, I was disappointed during the flashback sequences that they didn't touch up or completely reanimate Phoenix himself. Against the amazing looking young Klavier, he looked a bit crappy.
In general, I just would liked to have seen much more of a series progression. And with a new system and new set of characters this would have been the perfect game to bring the series forward. That's my main negative done.
What was here, in general, I really enjoyed. I was so glad that Case 1 was a bit more meaty and I thought it was an great introduction to the new cast. Oddly, unlike Angela, I really liked Case 2 and wasn't a big fan of Case 3 (mostly because of the investigation parts). I think it was the characters that drew me to Case 2, especially the noodle guy. And, yes, his harmonica animation was excellent.
Case 4 was long but it had me hooked. And while I thought the computer device maybe wasn't needed, what it amounted to and the way the information came together in that section kept it really interesting for me. The way the cases came together was all a bit neat admittedly, but I loved it and getting those final pieces to fall into place in that section had me actually excited. I thought it worked great.
I did think that Case 4 was slightly lacking in that it seemed to fizzle a little bit rather than come to some huge climax but it was still a satisfying end and the getting there was fun.
I was so glad we had a new cast. Yeah, pal, I missed Gumshoe and didn't think Ema MUNCH MUNCH MUNCH had anywhere near as much character but I think I was ready for a new story. Apollo himself was very like Phoenix but I liked that he felt a little more green all the way through. And the character touches like his impressive chords were nice. I like him and would like to see more of him. When I hit the end, because I was slightly disappointed with some elements I was left wondering what the reactions have been like. I was afraid, if they haven't been really positive, Capcom may lay the blame on losing the familiar characters and may well back pedal. Whereas, for me, I want to see where these new characters go and think there was a new dynamic created at the end that could move them away from the Phoenix/Maya relationship that Apollo and Trucy had throughout the game. Though I kind of hope Trucy ditches the magic outfit in the next one.
I loved Mr.Hat too.
So there you go. I enjoyed it. Some really good cases in there. But it was just another AA/GS game and I guess I was hoping for more and, even just being another one, PW3 had set the bar pretty high.
So... when is the next one out?
Edit: Gah! I can't hide spoilers! How do I do them?
Another edit: Got it.
