Well, I finally got an opportunity to hear EVERYONE'S voices, so here's MY opinions:
Arle (Alt.) - Eh, sounds a little TOO deep for my liking. but that being said, I'm going to take a shot in the dark and say Arle's Alt. voice is a reference to how Arle is a tomboy for the most part AND a Mythology Gag potshot at "Silvana's" English voice in the original Puyo Puyo.
Amitie (Alt.) - All I'm going to say is, the idea of Raffine teaching Amitie to be an upperclasswoman, and Amitie trying WAAAAAY too hard (and failing) to sound like one is HILARIOUS.
Ringo (Alt.) - Wow! Honestly, like MANY people have been saying, I'd actually prefer Ringo's Alt. voice be her DEFAULT voice for future games!
Rulue (Alt.) - Honestly, don't have too much of an opinion. Rulue just sounds WAY more feminine and chilled out in her Alt. voice. Don't get me wrong, I still love both voices though.
Suketoudara (Alt.) -Overall, I'm LOVING both his voices. As for his Alt. voice, I LOVE the fact that he becomes such a smooth talker. It's really funny.
Raffine (Alt.) - Ehh....Yeeeaaahhh....don't really have much of an opinion on her Alt. voice. I mean, I definitely don't HATE it. At best I can describe it as "Raffine: 1-2 years younger". That's about it.
Sig (Alt.) - Actually, I quite like Sig's Alt. voice. At least it has more emotion. Considering the JP version, I'm sure this IS intentional.
Klug (Alt.) - Headcanon time! I expect Klug to sound like his Alt. voice ALL the time when Lemres is around, while his DEFAULT voice would show up if he were to interact with....well, ANYONE else. That being said, I quite enjoy his Alt. voice and I'll probably be using it more than his default voice in gameplay.
Risukuma (Alt.) - There's something I find REALLY funny about Risukuma's Alt. voice. Maybe it's the fact that he sounds like Richard Nixon from Futurama.
Maguro (Alt.) - Just like with Suket, I'm LOVING Maguro's Alt. voice. Honestly, I think I like Maguro's more than 'Dara's. It sounds pretty endearing to hear him sound like such an adorably dorky smooth talker. If nothing else, it gives me some serious Incubus vibes...
Tee (Alt.) - Not bad. Not bad at all. As a matter of fact, his Alt. voice is honestly what I always envisioned his DEFAULT voice would sound like, if I'm being truthful here.
O (Alt.) - I guess O DOES sound pretty funny when he's angry, but otherwise I don't have much of an opinion.
Ess (Alt.) - Meh, she sounds...younger(?) I'll say this much, her Alt. voice (like Tee) sounds like what I envisioned her DEFAULT voice to sound like.
Ai (Alt.) - One part of me enjoys the fact that Ai basically becomes discount Scooby-Doo with his Alt. voice, and another part of me is a bit worried that that novelty WILL get old after a while.
Jay and Elle (Alt.) - Pretty CREEPY to hear THEM talk in such a monotone unison...and that sounds SO cool.
Zed (Alt.) - Pretty interesting. Just like with Tee and Ess, his Alt. voice is what I always imagined his DEFAULT voice be. Still, he reminds me of War Machine from the Marvel vs. Capcom games even MORE with his Alt. voice, so that's a plus in my book.
Schezo - Yeeeaaah...Schezo sounds...WAAY too OLD for my liking. I was sort of hoping he would have a more younger voice that would sort of compliment Arle's (default) voice. If nothing else, I feel like his default voice is trying to make some sort of very noticeable jab at the fact that our resident Dark Wizard is really 180 years old, despite his youthful body.
Schezo (Alt.) - I'm not saying I'd want his Alt. voice to be his default voice, but I'll say this much: Aside from a few hilariously unfitting voice clips, his Alt. voice fits his appearance MUCH more than his default voice, IMO.
Satan - Wow, just...wow. I honestly didn't think I'd be saying this, but....Satan sounds more evil and threatening than I EVER would have predicted! Why, he..he actually sounds...BADASS! (Wow, NEVER thought I was going to say THAT about this guy...) Still, what makes me laugh inside is that I bet the moment Arle and Carbuncle show up in a cutscene alongside him, or when everyone is blaming him for the chaos occurring in Story Mode, Satan's whole "evil badass" front will go right out the window faster than Schezo's "terrifying Dark Wizard" front whenever he says something perverted.
Satan (Alt.) - Effeminate Satan hilarity approaching! Honestly, Satan sounds like a discount James from Team Rocket, or at least trying his best to sound like him. Actually, when I listen even more, I start to think of/literally HEAR Oshare Bones...
Draco - For the first time, I finally get to hear truly clear voice clips of Draco, and I have to admit that I'm...liking what I'm hearing so far. I'll certainly say it feels pretty darn...unnatural to me that she actually sounds OLDER than Rulue of all people and likewise, I still wish her default voice would maybe sound at least a BIT younger but otherwise, her bold tomboy voice really fits her. BTW, anyone else getting some Succubus vibes from her default voice? No? Just me? All right then.
Draco (Alt.) - Aside from a few admittedly..."grating" voice clips, Draco's Alt. voice is essentially what I always envisioned her to sound like in English with her default voice serving as the Alt. That being said, I quite enjoy both voices. Her default voice really lets her boldness shines though, while her Alt. voice emphasizes her more cuter traits, in a manner of speaking.
Witch - Good heavens...I won't lie, her default voice sounds even MORE jarring to me than Draco. At least I can give Draco a pass for being a Tomboy, but Witch is just...I mean for WITCH to sound just as old as the likes of RULUE of all people (if not OLDER!) is just SO...weird to me. Like, I can't really describe it. I'll have to hear more before I can say whether or not I like it. For now, I'll just say I can tolerate it.
Witch (Alt.) - I guess Witch's Alt. voice comes CLOSER to what I always envisioned her to sound like in English, but it still sounds a bit old, even for her. Just like with Draco, I don't hate her voices, but I can't say I'm a huge fan of them either. If I ever get PPT, if nothing else I'll probably use Witch's Alt. voice more often, if anything.
Lemres - My, my. I think I can safely say that Lemres really...surprised me. He doesn't exactly sound like how I envisioned him... like, at ALL. But you know what? In Lemres' case, I think that was for the best. If nothing else, I actually REALLY like the default voice SEGA went with for him. He sounds like his personality usually entails. He's really just a truly chill guy at heart who's really easy to make friends with, once you get past the pretty suspicious and shady behavior.
Lemres (Alt.) - Alright, let me get this out of the way right now...SURFER-DUDE/HIPSTER LEMRES FTW!!! OK, there. I got it out.
Feli - I guess...Feli isn't BAD, per se. It's like Feli's English VA got her overall personality right, but there should at least be a bit more emotion to her than monotone. I just can't see Feli sounding monotone 100% of the time. I see it working for Sig, but not her. At least, I hope she doesn't sound 100% monotone in her second post-battle cutscene when the cast uses Lemres to check if she's returned to normal. It's best to say, she should have a more "mystical/mysterious" inflection to her voice, if that makes sense.
Feli (Alt.) - Sooo....remember when I said Feli probably shouldn't sound 100% monotone and that she should have a more "mystical/mysterious" inflection to her voice? To me, Feli's Alt. voice makes her sound like she is REALLY phoning it in and at the same time, not phoning it in ENOUGH. Like, she's not really..."TRYING" to make said "inflection" work, if that make sense. Honestly, I can't say I'm a fan of it...
Ecolo - Ecolo actually sounds adorably silly, if I'm being honest. Something about his default voice gives me the same feeling I get hearing Jay and Elle. Just like them, I don't dislike his default voice, though I'm not too hyped over it or anything.
Ecolo (Alt.) - Not...really much of a difference from his default voice, aside from the obvious fact that his voice clips have all been GREATLY sped up. Honestly, did Ecolo's English VA even record new lines for his Alt. voice? Still, I will give Ecolo's Alt. voice this much: Ecolo + sped-up voice = Pretty gosh-darn funny voice clips.
Ex - I quite enjoy his voice clips. Heck, if I'm being honest here, Ex's English voice is almost PRECISELY what I envisioned for Schezo, and/or ESPECIALLY Lemres to sound like. Don't get me wrong though, Ex's default voice still greatly fits him.
Ex (Alt.) - Not bad at all. I like Ex's Alt. voice overall. Still though, I have to ask all of you...did anyone ever expect Ex to sound so...INTENSE?
Hard to say, the thing is that SEGA is once again enforcing embargos, on story related content, like they did with Chronicle, so odds are that we may not see much english story mode material for a while.
Actually, SEGA themselves said that once the game is officially released to us, you can stream whatever you like. Story Mode included. They're more than aware that a series as obscure as Puyo Puyo NEEDS the publicity.
