Ok. Put it this way. I would call this a sci-fi game , not a Fantasy game. Cat ears are meant for anime, MMORPGs (Destiny is NOT an MMORPG, just so you know), and obviously, cats. Let me give you an idea of what sci-fi is. It is a movie usually based off of extraterrestrial communications, amazing science advancements that haven't happened yet, or even the unknown. For example: Halo is a sci-fi game and does NOT need cat ears because it won't fit and would look wrong. Predator is a sci-fi film about an alien that likes to hunt humans and claim their skulls as trophies. Cat ears would look stupid on an alien such as the predator. Fantasy is different from sci-fi. I don't know if you are a troll or not, but regardless, this should sum it up for you.
