I agree, being rated M could really help Destiny's​ story. Having some dark cutscenes of Eris's team being ripped apart by the hive would have really made us hate crota more. Having some more adult jokes​ from cayde 6 would be great too (if you think about it, this adult human who was turned into an exo, would not be censoring himself when he's talking to an adult guardian). Even having the fallen swear occasionally like the Covenant does in Halo would be great. Being rate T for teen just waters down the idea of a gruesome space war so it's kid friendly.
