So I have had a thing with hats here, and the other day I discovered a very neat feature!
I got the headpiece you see in the picture, something with a mask. That in itself is not to special, but to my surprise the voice of my character was changed in the coming dialogues (!). There is a filter added to the voice so it actually sounds like he is talking from within a mask.
I'm not sure if this is the common thing to do, but a really nice, and for me, unexpected design feature. And as opposed to "Who are you?" this absolutely adds to the gaming experience!
