Myself Id say SFB course I did like the differant size Photons and phasers of FASA tho Kinda made since, but I did not like the way the did their shield rules where each shield was independent of the others, as in the show and movies when the captain said raise shield all of them came up.
I am torn a little on the engines, but I think FASA did them a little better.
Plasma torpedoes have to go with SFB
Cloak Again sfb developed it a bit better
Not too sure what else we could compare
But one thing I did dearly love about FASA is the star ship Constrution manual, which I got pretty good at making some very efficient ships especially the smaller ones.
So if you'ved played both what do you think about both
