How do people generally rank the games? For me the third game is the best in the series followed by 1, 4, then 2. However the last case in 2 is one of the best cases. Have not played the spinoffs or the 5th game. I burn out on the games easily despite liking them.
Out of the mainline games I'd rank them 1 > 3 >> 6 >>>> 5 >>>>>> 2 = 4. I really love 3 as this epic conclusion of the original trilogy, but I feel like 1 is the stronger game if only due to being standalone. It tells a really nice story on its own, I love the 5th case that was added after the fact and out of all the goofy standalone cases this series has had Turnabout Samurai has got to be my favourite, that Steel Samurai stuff was so memorable.
Anyway I think people usually rank 3 first, and 1 second, like you. Investigations 2 tends to rank highly as well if we're talking spinoffs, I'd rank it highly too.
So yeah, you've got Investigations 1 and 2, you mention you haven't played those. I1 is a lower tier Ace Attorney games, though I find all of them to be enjoyable. I'd still rank it higher than 2 and 4 because of how it shakes up the formula though. But Investigations 2 is an amazing game (with an amazing fan translation might I add. That one is top tier AA, though it's definitely dependent on the first investigations game. So those are worth playing.
Anyway, those two are neat especially because you can take Ace Attorney 1, Investigations 1 and Investigations 2 and you've got yourself a pretty damn compelling Miles Edgeworth trilogy
(And then you've got Professor Layton vs. Phoenix Wright... now I enjoy this game, but I also like Layton games to begin with, though I definitely prefer Ace Attorney. It's definitely more of a Layton game in its overarching story, but it does have some very nice in the moment character writing. There's this Maya and Phoenix scene that's as memorable as any top tier moment in the main series. But I really have trouble ranking that one as an Ace Attorney game.)
Should I finally jump into this series on the 3ds?
I'm very bad at visual novels - and actual novels. However, I love reading non-fiction.
Should I give it a go? Or is it only for those who really like vn's?
(I haven't played VLR/999/etc...)
Ace Attorney can get obtuse in its puzzle solving mind you, but that doesn't seem to be your issue and it's still as accessible as vn's get. You won't be going through huge walls of monologue or anything, these games tend to read pretty well, it's snappy. The Trilogy release on 3DS would be mighty fine buy.
