As this got me looking around for oddities in starting language skills, interesting shift from RMB 98 (right column, bottom)
Literacy: Dragonese
Literacy of Choice (probably American)
Basic Math
to RUE 158 (right column, just before weapons and equipment)
Language: Dragonese
Literacy: Dragonese
Basic Math
Fundamentals of Magic
Notably it appears that originally Hatchlings could read/write 2 languages but not speak ANY of them unless that was chosen as one of their 6 skills, but in RUE they swap their other-language literacy for being able to speak dragonese and know magical lore.
That seems like a pretty good deal (2 for 1) but in RUE dragons only get 2 optional selections now to start instead of 6!
The only compensation seems to be that now you can kidnap Rogue Scholars (RUE93) and force them (under threat of digestion) to teach every single secondary skill they know to you, before eating them anyway.
Of course back in RMB, it appears they didn't used to list native languages. RMB 31's description "speak in a language other than their own native tongue" seems to support that everyone knows a native language (I don't like that, the option of a Vagabond/Scout who doesn't speak ANY language sounds cool) though not at what %...
I think I recall only HU2 having basic rules for skills EVERYONE knows, which for some reason includes driving cars.
Getting back to the Cyber-Knight, pg 63 of RMB stands out as listing American/Dragonese+2 which might even exist IN ADDITION to the usual "free native language" that RMB seems to imply exists for all of the classes.
The primary question being: since Dragonese is obviously their native language, does the literacy that dragons get in a 2nd language imply they speak the language too?
Pg 64 also had '2 of choice' for the glitter boy... so they started with 3 total in 1990? Pg 70 a Juicer began knowing 4 languages?
Perhaps the native language of all Glitter Boys was French, and the native language of all Juicers was Portugese?
One semantic difference notable on RMBp72 in the body fixer and pg 76 for the Cyber-Doc. Their Language is "1 additional" whereas we don't see the word "additional" for the GB/Juicer "of choice" notations, possibly implying their native language was meant to be included in there? The Scholar was the same: "Two additional languages of choice" rather than "Two of choice" like the Glitterboy on page 65.
81's Wilderness Scout had "choice of three" resembling the "three of choice" a Juicer has on pg 70, with no "additional" like the the fixer/doc/scholar implying a native language...
Then 82's "Vagabond Non-Skilled" (we tend to abbreviate that often) who is "American and one language of choice". Does that imply American was the native language, or in addition to it, meaning the BONDS knew 3 to start?
LLWs (85) and Shifters (89) and TWs (90) had "two additional", Mystics (86) had 1D6 additional, so they're like the fixer/doc/scholar rather than the CK/GB/Juicer...
Bursters (104) and Coalition Stalkers (107) both had "American and one other" like the vagabond (unclear if 2 total or 3 total) while Wild Stalkers (106) and Mind Melters (112) had "American and two other" (unclear if 3 total or 4 total)
Dog Pack (110) infamously had "American and Dragonese" hinting at a subtle relationship existing between the Dragons of North America and it's Psi-Hounds which remains a mystery to this day. Is that two total, or do they speak the human/dragon tongues in addition to their native barking dog language whose name we don't know?
RUE curiosity: pg 94 the Rogue Scholar "Speaks Native Language" and pg 96 the Rogue Scientist "Language: Native Tongue". Why are scientists so much more Vagabondy?
