What DOES make good dialogue? I need to know, because I'm trying to write some...
Like, I'm doing a short tech demo in Game Maker. For part of it, I'll do some voice acting (tomorrow there are only going to be like, two people in this building, so I'll be pretty much unrestricted on volume, which is what destroys the quality of pretty much all my previous attempts.) for dialogue that appears on screen. Thing is...I know what I want to say, just not how best to say it.
The theme is Castlevania. It's the very last boss, and the mood is of course, very tense. The characters are you, (typical hero guy, cept this about the third time you've done this, so you have experience) a powerful priest, (think the pope, but EVIL-EVIL-EVIL-EVIL-EVIL) and someone dear and important to you (they'll be hanging from a cross, behind the priest. Could be either gender at this point. But there won't be any gay thing going on here, that's not what I mean. I'm actually trying to avoid romance, unless of course, it would help the dialogue. That aside, this person won't be talking.)
So considering that situation, what should I do to make it sound best? Not only the words themselves, but what tone should I take with each character, what kind of voice? Should the priest haev a deep, booming voice, and should it sound like a lion's roar every time he opens his mouth? Or should he seem raspy and decrepit? Also, the hero. Should he seem pained that his firend/whatever is hanging limp in front of him, seemingly dead, or should he be filled with righteous anger?
Help?
