I think it's better for the ogre to move somewhere like in farm or in the tower.Among girls there are:
9 Humans
1 Halfling
4 Elves (2 High, 1 Dark, 1 Swamp)
3 Giants
1 Ogre
5 Goblins
1 Minotaur
1 Batgirl
1 Were-Spider
1 Dragon
3 Vampires
1 Imp
2 Succubi
There was 4 species of Goblins in the game & a big enough fanbase for them that not having one of each in the final harem would have upset alot of fans.
Theres plenty of diversity among the monster/creature girls so i dont see the problem?
