Just to follow up on the voice acting...
I think the voice acting is pretty bad, but not quite as bad as Final Zone II, which I think might be the worst (Last Alert's was bad too, but not as bad as everyone claims. It just had some really cheesy dialog). I think Logan's voice actor is pretty good himself, but the thing is that it easily sounds like a 30-year old man and Logan is NOT a 30-year old man ! Also that green haired chick had a really bad voice actor.
For god sakes there are lines like "A fine Marnin to you Ma Lard" being done with incredibly fake accents. The dub is just horrendous the only game I can think of that's comparably bad on any platform (Last Alert included) is Castle Shikigami 2 for PS2.
Come on now, seriously. Seriously. No game tops Valis III.
It's not simply bad, poorly acted and/or scripted.
It's really just in a league of it's own.
"EEEVen thuh migh-tee Ramses izzz, taaykin-me forawimp. Askin' me tuhdo-battle-with-a GHURL."
"Hey...... just cut the conversation. And watch out for my whip."
And as for Dragon Slayer, the last in-game voice I hear in the game is:
"A fine Marnin to you Ma Lard"
"Good morning Malasis..."
As soon as the opening chat is done, I turn the voices off and have done so ever since after playing it through the first time when the Turbo Duo was first released.
And most of the times I've finished it(I played it through like 30 times in row and then maybe once since) I just walk away once the final bosses is dead.
