At the beginning of the game, you have no contact with other races, bar the Amoeba, and there's no reason you'd employ an Amoeba because they could be an enemy agent.



So I'd suggest that heroes that appear in the roster should be of your own race, OR of a race that you are at peace with.

The suggestion is similar to /#/endless-space/forum/28-game-design/thread/12220-hero-recruitment-only-out-of-your-own-race

This thread has been linked to the former and is moved to the archives.
