I just noticed this thread and it got me wondering just how many 0-level dudes are equal to characters of various levels and how well regular modules work with level-0 characters.
Most parties in modules are 4-5 characters, I think, so 4-5 level-1 guys must be somewhere around 16 level-0. Maybe a 4:1 ratio is about right, since the level-1 guys have better hit points and probably better equipment. In general there isn't a lot that level-1 fighters can do more than a handful of level-0 guys, although clearly the level-0 characters don't have access to spells that clerics and magic users would have.
Imagine trying to run level-0 guys through some of the old Gygax adventures which are designed for parties of levels 10 to 12!
Nice write up, by the way!
