Player Character creation

Acquisitions Incorporated:
Character creation remains standard, however, eventually in the story, you will be asked to select a company position from the Acquisitions Incorporated book detailed on page 18. If you enjoy pre-planning your choices you may want to have a look at them during character creation. The company positions include features that improve as your franchise advances.
Rolling stats: For 3 stats you roll = 3 times 3d6 with minimum numbers of 3, 5 and 7 then for the other 3 stats, you calculate 23 - roll1(minimum of 5), 25 - roll2(minimum of 7), and 27 - roll3(minimum of 9)   an example which you could use on roll20 would be:   /r 3d6
/r 3d6
/r 3d6

this might result in 11, 14 and 6(this gets rounded up to 9), so next you calculate:
/r 23-11
/r 25-14
/r 27-9
our final stats would then be 11, 14, 9, 12, 11, 18 to assign as you please.

Acceptable sourcebooks:
I would encourage the use of the backgrounds included in the Acquisitions Incorporated book, but all content in published dnd 5e books from WotC should be acceptable.
