also if you can while animations are harder to pull off it could be cool to see animations and maybe making the game go 1 person per turn with each person having only 1 attack instead of these 3-5 attacks
another thought is always having a leader as stated for the girls it could be a queen or goddess while the monsters or breeders side it could be a demonic or a king
alt you could even make your own bosses like choose your army style so if i wanted to have my queen be a futa on the breeders side then i could while another person might choose a huge minotar
