No one else playing this game then? I remember when all we talked about was the DS, what happened?
Anyways, I'm really enjoying it. I'm on case 3 now (Which is fan service central that one, and pretty hilarious too), and although it does lose a little something from not having any courtroom stuff in it, the actual investigation parts are paced a whole lot better. Remember how in the older ones you would have a ton of different rooms to go to and sometimes it would involve finding some needle in a haystack like evidence, or presenting something random to somebody? Well, they seem to have fixed this. You're sort of limited to a single room in this one for each little investigation you do, and in these 'rooms' there are usually a few people to talk to, and evidence to find.
The fact that you can actually walk around makes finding little bits of evidence a little bit easier, and once you've found all of the evidence in a given area you usually have to combine pieces of 'logic' in order to discover in slightly more detail how the murder went down. After that it's usually just some cross examining in the way we all know and love.
So yeah, if the next game in the series combined the new investigations with the already awesome courtroom stuff, it could be the best Ace Attorney game ever. (Assuming it has a good plot, of course).
