Here are my answers to the top 10 Questions from Random Wizard, from a couple of weeks ago. Yes, I know I’m slow.

(1) Race (Elf, Dwarf, Halfling) as a class? Yes or no?
Either. I’m current using Race as Class in Microlite81. I generally prefer race and class separate, but it’s not a strong preference.

(2) Do demi-humans have souls?
Some do. Some don’t. It depending on what setting I’m using. This is one of those questions that really should not be determined by the game rules but should vary by the setting of the campaign.

(3) Ascending or descending armor class?
It really does not matter to me, mathematically they are the same (and there are a few other ways to do it that are also mathematically equivalent. I use ascending AC for Microlite74 and Microlite81 because they are based on Microlite20 which uses ascending AC, not because I think it is somehow inherently better. That said, new players today generally seem to have more problems with the math required for something like THAC0 than they do with the math for ascending AC.

(4) Demi-human level limits?
Yes and no. In a game with an upper level limit for human characters of around 14-15, they work okay. In more open-ended games, I prefer no level limits, but require quite a bit more XP from demi-humans.

(5) Should thief be a class?
I would prefer that thief just be a background that a character of any class could take. However, the thief class is so strongly associated with D&D, that it also has to be present in any D&D-like game. I strongly object to the idea that the thief should be some type of skirmisher/fighter lite as WOTC editions (and 2E, tio a lesser extent) do with the “Rogue” class.

(6) Do characters get non-weapon skills?
I prefer to use backgrounds to skills. Characters select a background for their character and then have a better chance of doing things strongly associated with their background and class than they do things that are only loosely associated (or not associated at all with either).

(7) Are magic-users more powerful than fighters (and, if yes, what level do they take the lead)?
They are weaker than fighters at low levels, on a par with fighters at mid-levels, and somewhat stronger than fighters at high levels. High level fighters, however, can go toe-to-toe with high level mages with a good chance of success, especially if they have a good plan of attack.

(8). Do you use alignment languages?
They are there but are seldom used in public. There main use is in religious ritual and secret societies.

(9) XP for gold, or XP for objectives (thieves disarming traps, etc…)?
Both.

(10) Which is the best edition; ODD, Holmes, Moldvay, Mentzer, Rules Cyclopedia, 1E ADD, 2E ADD, 3E ADD, 4E ADD, Next ?
I like BECMI/RC, OD&D, and B/X the most and have little love for 2e with the Player’s Option stuff, 3e, or 4e. No opinion on Next until it is finished, but so far it looks like it would be middle of the pack somewhere.

Bonus Question: Unified XP level tables or individual XP level tables for each class?
Class-based advancement helps solve many balance issues so I strongly prefer it. However, you can do it with separate XP advancement tables or with a unified table and multiplier to XP earned for each class.
