(1) Race (Elf, Dwarf, Halfling) as a class? Yes or no?
I’d prefer them to be an option but not a requirement. If someone wants to play a halfling as a class rather than a halfling thief (or vice versa), why should I care?
(2) Do demi-humans have souls?
All living things have souls. The real question should be what kind of soul? Immortal or not? Rational or not?
(3) Ascending or descending armor class?
I’m happy either way. THAC0 is just BAB with a different name.
(4) Demi-human level limits?
I’m happy either way. If I’m the GM, I’d likely not use them.
(5) Should thief be a class?
Duh. I’d get rid of magic-users before I got rid of thieves.
(6) Do characters get non-weapon skills?
Not necessary, but I do like to have a skill resolution system even if there aren’t defined skills in the game.
(7) Are magic-users more powerful than fighters (and, if yes, what level do they take the lead)?
I’ve never really understood the argument that magic-users are the most uber of classes. Are they powerful? Sure, even at 1st-level, where sleep is a game-changer. For one encounter a day. Maybe. There are simply too many variables to say that, all things being equal, magic-users blow fighters out of the water.
(8) Do you use alignment languages?
I have used them, but not since 1E.
(9). XP for gold, or XP for objectives (thieves disarming traps, etc…)?
I reject the fallacy of the false dilemma. My answer, “Yes, please.”
(10) Which is the best edition: ODD, Holmes, Moldvay, Mentzer, Rules Cyclopedia, 1E ADD, 2E ADD, 3E ADD, 4E ADD, Next ?
I have no experience at all with 4E or Next, so I can’t say for sure. I have a fondness for the earlier editions, but which one’s the best? I don’t know. Best at what?
Bonus Question: Unified XP level tables or individual XP level tables for each class?
I have no real preference.
