|I think this was from the old Legends of the Void book.|
I also need to name it. This is often my biggest failing when it comes to this sort of thing.
What I was planning on doing was playing some solo fleet style or patrol gaming, and using either Swords and Wizardry, D20 Microlite, or Dungeon Squad to play the boarding actions. I also have the old Mongoose 'Seas of Blood' expansion from days of Yore to play with, if push comes to shove. That system was a little long on the maths, but worked relatively straightforward for ship to ship combat and crew casualties.
Then, once it was done, post a gaming report, maybe in the manner of a captain's log from the Insidious Illithid's perspective?
