the "expanded architypes" could be as simple as for example: adding some of the dead clans/and or unlisted modules that got left out of atow but some people have been asking for.
or it could be some additional precreated charactors example:
clan mechwarrior
clan pilot
washed up mechwarrior
grizzled tech
solaris mechwarrior
lostech prospector
dropship captain
young noble
etc
those are all sample chars that were made in the past
expanded weapons could include, additional generic, and or specific weapons like the one shot cc gauss pistol etc.
more gear could include more "non generic equipment"
like the sldf neural helmet with its +1 bonus to piloting skill checks err -1 bonus to target # in this version
now what I personally would like to see is some blurbs on specific weapons similar to the
"Mandrake holdout gauss pistol
developed for laio's Maskirovka, the mandrake gauss pistol is an easilly concealed single-shot gauss pistol.
Covert agents especially prize the Mandrake for its carbon-ceramic casing, which prevents standard metal detectors from detecting the weapon (though the ammunition must be carried seperately and disguised). Additionally, the Mandrake cannot be detected by chemical or spectriscopic analysis because it uses a stored charge rather than chemical propellants. Concequently, Maskirovka operatives can carry their Mandrakes through any spaceport in the inner sphere without detection. Once fired, the weapon cannot be recharged or rearmed and is usually disgarded.
Aparantly both the miio and loki are attempting to duplicate the mandrake, but neither has been able to produce a working facsimile. Rumor has it that the NAIS is offering a reward for a functioning Laio Mandrake.
