really? i wanna know lol. it would be so wierd.

Yes, and there's a mod out that makes killing Nomads increase your rep with every faction, including the Nomads. It's called Friendly Universe, if memory serves. Have a look at that if you want to learn to mod the Nomads to be friendly.

Change, in the group fc_n_grp only, all the {empathy_rate = ****, 0}

ps: the friendly universe will do: if you kill 20 nomads every faction, including nomad, will be fully friendly.
