So this is going around and I'm afraid I've caught it.
My guess? Not enough Vitamin C.
As I intend to dedicate the month of August to discussing Dungeons & Dragons (Wait? What? Really? I said that?), consider this a coming attraction to the level of quality ideas and entertainment you're in for.
Oh, you're in for it alright...
(1). Race (Elf, Dwarf, Halfling) as a class? Yes or no?
No. I thought that was silly in 1977.
(2). Do demi-humans have souls?
Dwarves have souls but lack spirits.
Elves are fae and do not have souls. They have spirits and can become spirits.
Half-Elves, like Humans, have souls and spirits but sometimes only half of each.
Gnomes, like Humans, have both souls and spirits but only one at a time.
Wilders, also called Halflings, like Humans, have both. One is usually stronger than the other.
(3). Ascending or descending armor class?
(4). Demi-human level limits?
Hahahaha...oh. You're being serious. No. Silly in 79'.
(5). Should thief be a class?
Should anything? Sure, why the hell not.
(6). Do characters get non-weapon skills?
You mean can they learn to cook, sail and weave wicker baskets? Sure.
Knock yourselves out.
(7). Are magic-users more powerful than fighters (and, if yes, what level do they take the lead)?
Wizards are better at using magic.
Warriors are better at fighting.
Apples do no 'take the lead' over oranges at being oranges and vice versa.
(8). Do you use alignment languages?
Yes, I speak good.
No, you speak well.
I do, I speak good well.
(9). XP for gold, or XP for objectives (thieves disarming traps, etc...)?
XP for making your character seem like a character, discovering things, inventing things, solving problems and the like.
No XP for gold. That's like giving you a penny for finding a penny.
(10). Which is the best edition; ODD, Holmes, Moldvay, Mentzer, Rules Cyclopedia, 1E ADD, 2E ADD, 3E ADD, 4E ADD, Next ?
After that, Sworld World.
Bonus Question: Unified XP level tables or individual XP level tables for each class?
Huh? Oh, unified. The less tables the better.
Let the Hate Mail Commence!
