Destiny is further described as “fun and accessible to all,” aiming “to create a universe as deep, tangible and relatable as that of the Star Wars franchise.” Based on the language in the document, it appears that Bungie aims to create a universe accessible to multiple demographics, perhaps suggesting that Destiny will be less mature than Bungie’s efforts with Halo. A quote from Bungie co-founder Jason Jones says “Destiny is designed for your inner seven year old. We want to make it feel like a mythic adventure.”
So it's Halo for kids.
