I love the idea of an expansive world built in Indian mythology, with a focus on an Archer class (story of Arjun, Krishna, etc). Ideally would be a 3D game at the level of God of War, but I can totally see a 2D rpg with amazing story (more along the likes of HollowKnight or Celeste).
I would love for the world building to be the focus of this. There is so much to explore in Indian mythology, with so many characters and so many stories. It could honestly even be more open world, since there are so many different paths that could be ventured and explored in the mythology, with all of them connecting.
