I go for a mixture of factions. Don't like Angels much. I'm good with all factions. Alien races tend to be overrated. I know their traits and other stuff. But did you know you can create factions? My bro created a faction and just spammed the social engineering table. +4 everything. lol
Anyway, GO DRONES: the Aussie race. I clocked them as librarian, great faction for producing forces with a planned economy. +3 industry!
