The current version has a table for creatures in that section that contains the following:
* Name/variety of creature
* Level, outlook, archetype
* Movement type, rate, and max pace
* Exhaustion/endurance modifier
* Size and crit modifiers
* Hits and death hits
* AT, DB
* Initiative modifier
* Attacks with OBs
* PP
* RR modifiers
* Skills with bonuses
* Biome
* # encountered
* Frequency
In comparison, RMFRP also used tables for creatures in a given section containing:
* Type of creature - same as RMU
* Level - as RMU, plus a random variation factor
* BMR - as RMU
* Max pace, maneuver bonus - RMU puts max pace in with movement type, while the maneuver bonus is listed as a skill
* Speed MS/AQ - this is used to vary the DB by posture and to look up the initiative, on a different table at the beginning of the book. RMU just lists the initiative mod directly, and any variance in the DB would be based on dodging etc just like a character.
* Size and crit modifiers - as RMU
* Hits - as RMU
* AT, DB - as RMU
* Attacks with OBs - as RMU
* # encountered - as RMU
* Treasure type
* Bonus experience - not relevant in RMU
* Outlook/IQ - outlook appears in the RMU column with level
So what the big table is missing is only treasure type and IQ.
RMFRP also lists some codes next to the name of the creature in its individual listing. I... have no idea what those mean, and can't find any explanation in C&M.
RMU also has a block next to the individual creature which includes:
* Category (e.g. Animal-Carnivore) which corresponds to which big table you should check
* Archetype (also appears on the big table)
* Variant types
* Size in numerical units (e.g. feet and inches)
* Armor description and AT (but the AT also appears on the big table)
* Treasure type
* Realm
* Miscellaneous notes
* Stat bonuses
* Talents and flaws
Of those, the only one that RMFRP put on the big tables in C&M that RMU doesn't is treasure type. All those other things either appeared in the text or they weren't provided at all.
Now that said, I would have loved to toss the big tables and just have a complete stat block for every creature. But that would have been a twelve volume set or would have required drastically cutting the number of creatures.
