Here's my answers to Random Wizard's Top Ten Troll Questions for Your Game
(1). Race (Elf, Dwarf, Halfling) as a class? Yes or no?
a - depends on the ruleset. As I'm currently running DCC, I'll go yes
(2). Do demi-humans have souls?
a - sure. animals too while we are at it
(3). Ascending or descending armor class?
a - either or - I'm a fan of S&W and it's flexibility in this matter
(4). Demi-human level limits?
a - except for halfling fighters, do we ever really hit it?
(5). Should thief be a class?
a - yep. but I prefer bards ;)
(6). Do characters get non-weapon skills?
a - ACKS is about as complicated as I would get with this, but yes
(7). Are magic-users more powerful than fighters (and, if yes, what level do they take the lead)?
a - fireball is the game changer in classic / AD&D - in DCC, I think it balances a bit better as all of the classes can bust out beyond the others if lucky with their rolls
(8). Do you use alignment languages?
a - say what? never have
(9). XP for gold, or XP for objectives (thieves disarming traps, etc...)?
a - gold, killing, special achievements and the like
(10). Which is the best edition; ODD, Holmes, Moldvay, Mentzer, Rules Cyclopedia, 1E ADD, 2E ADD, 3E ADD, 4E ADD, Next ?
a - 1e if I had to choose, but I like them all and their little clones too!
Bonus Question: Unified XP level tables or individual XP level tables for each class?
a - really depends on the system - in AD&D, those xpo tables are part of the class balancing
