I just thought of the worst idea for MGE based game, "Stalked by Mamono" on Oculus Rift. You are walking around in the virtual sim world, as you look around, there is a monster girl (random pick depending on enviroment) looking at you. You walk or run away, but she is following. It'd be totally freaky.
Enviroments:
Home: Devil Bug (It'd be crawling towards you), Nurango, Living Doll (seeing one walk off the self would be scary), Juragumo, and Lesser Succubus (The scariest one yet...)
Meadow: Slime (all Execpt Bubble), Weresheep (Could you imagine one walking towards you, going 'Baa baa'? ), Wererabbit (Hopping towards you in virtual reality, now that's scary), Unicorn (That would be nice actually)
Forest: Alraune (She is one that won't chase you) , Arachne (Arachnophobia alert!), Dryad (see Alraune), Centuar (good luck outrunning her), Honeybee (getting chased by one would be cute), Giant Slug (getting chased by one would be funny)
City: Baphomet, Inari (and all her fluffy tails)
