I had wanted to design a game in Unity where you play as a 1 foot goblin or kobold type creature and you have to trap and capture elves to butcher for meat.

You could start by capturing weak and small elves and eventually work up to the queen who is taller and more difficult while able to use magic.

Elf parts can be harvested and used to craft armor and weapons or more traps. Imagine that Attack on Colossus game. Maybe in VR.
