Borrowing from the game Urban dead.. I think it would be cool to be able to examine players and be given a back story/description that said players created for themselves. The examine feature could also give valueable information. What items they have equipped, what moodles are affecting them, how much they are weighed down. NPCs, could have genericly created descriptions and real players could have that function to if devs still plan on making it possible for players to hide among NPCs.
