I searched and I don’t believe I found anything for Destiny under the positive examples yet. My husband plays this game a TON, and has both male and female characters, and the entire time he’s played I don’t think I’ve ever noticed any kind of “sexy” looking armor. I asked my husband and he says he hasn’t noticed any either.
Honestly after searching, the closest I’ve been able to find to anything under “sexy” would be the Queen of the Reef, Mara Sov.
I haven’t had a chance to play much of this, but given that I can’t find a single promotional material from them that goes for the “sex sells” angle and that it’s from Bungie (the creators of Halo) – I am pretty confident that it qualifies as a positive example.
