Many thanks for this mod, which is really adding challenge and atmosphere to the game with the extra factions!
It shows also that a lot of work was done, so congrats to Monaldinio.
If I had a suggestion, this would be to augment the feeling that Chiron is vast and hostile, at least with an optional setting. When I was playing SMAC-X (on highest difficulty), it took a long long time before I could feel safe from Worms... Here things appear to be much more calm, even with 'barbarian hord' option. Perhaps for whose like me who like to suffers the wrath of Chiron, another setting should be added, with more advanced life forms, or the planet going to sentience faster, I don't know.
Also, in the original game, the worms were invisible most of the time. I think this was also the reason the player never felt really safe for a long time. You never knew if a worm would not appear and destroy a former for example.
