The game was an RPG were you get into the dungeon and start to move around doing quest and other stuff.
I remember you get to be the father of the dark haired demon lord's child.
If i'm not wrong, it was a game with 3 releases.
Played it on my PC 5 years ago, if not more.
If not being on the wrong mixing games, when on dungeon, you move on a 3D space on POV.
Sorry if it's too little info, but hope someone remembers the name.
List anything you think it could be.
Thanks in advance!
