You can stack most mods together, and many of the more popular mods have their own compatibility mods to go along with SFO. Depending on what mods you use, the game will usually only let you launch it with around 65-70 mods. I basically mod the game specifically for the faction I'm playing. I highly recommend the Kraka Drak mod, which has its own SFO compatibility. Completely new and original dwarf faction that lives in the chaos wastes.
