This does feel rife with potential issues when applied at the individual character level, as much or moreso than alignments.
Do you have to be seen to be playing your character traits consistently in order to gain their benefits? Who judges that? Are there out-of-game moral / ethical issues when it comes to providing game-mechanical rewards for being xenophobic? And are we talking fantasy xenophobia between, say, elves and dwarves, or are you legitimising players expressing real-world racism?
It's a port from the Stellaris game. Xenophobic ranges from isolationists to genocidal.
In game they get cheaper expansion costs and growth rates.
I'm thinking of mapping various abilities to the ethos. Eg militaristic might get weapon and armor proficiency like dwarves and elves.
Militarists get combat bonuses.
Daleks would be fan xenophobic, Militarist and fanatical purifier civic.
