capital_scope = {
                every_tile = { kill_pop = yes }
                best_tile_for_pop = { create_pop = { species = "species1" ethos = owner } }
                best_tile_for_pop = { create_pop = { species = "species2" ethos = owner } }
                best_tile_for_pop = { create_pop = { species = "species3" ethos = owner } }

home_planet = {
                create_pop = {
                    {species = "species1" ethos = owner }  #try1
                    {species = "species2" ethos = owner }  #try2
                    species = "species3" ethos = owner    #try3
