I just wondered today - you already created a lot of undead versions of existing monsters, but would you also plan to add opposite (binary) gender monsters where it makes sense ? Lions, Tritones and Eldjotnar have both (binary) gender and it is really cool.
Here is a list of what I think the game misses : Centaurides, female Undeads (Zombies, Lost Souls, Draugs, Phantasms), female Arachnos (Arachne could also be the only one), male Djinns, female Yetis, female Neanderthals, female Yerrens, female Trolls, male Elves, female Jotnar, female Dvergrs and Oceanids (with Potamoi).
For these ones I'm not quite sure about the results : Jackalwomen, Tigerwomen, female Nightstalkers and female Coral Guardians.
