Maniac
Apolyton Sage
Santiago and strangely Morgan are most likely to go green beside Deidre.
I don't have that experience with Santiago, but I do with Morgan. Weird. I have no explanation for that. Though I don't yet exclude the possibility I just remember it better when he goes green because it seems so out of character.
@ spawning date of the new factions
Alternative ways of spawning the SMAX factions are not ruled out. However I consider the most important reason to add the SMAX factions making diplomacy more interesting, especially re the Planetary Council and Concordat Council. This means that I wouldn't mind if the SMAX4 were always weaker than the SMAC7 in terms of unit and base count. But I would want them to always at least *exist*.
