I'm a little unclear on what you mean, Ayrin. Do you mean different appearance, different stats, or perhaps both? I kind of like the idea of tweaking the appearance a little bit, so maybe the three soldiers have different facial textures (when I first played Goldeneye and saw that the Russian soldiers had different faces, I was blown away), but I suppose varying their stats might be cool as well. One might be especially tough and have an extra 25hp, while another might be a little weaker and have -25hp. The "both" option could increase variety even more, perhaps to an extreme. For example, one of those three swordsman might have no shield, but have a big two-handed claymore, giving him worse armor but a higher attack. That might be taking it a bit too far, though, especially since that would require new modeling and animation.
