I have not been playing it, but I did watch Dave Bagnall‘s Dishonored Let’s Play.  It has something to do with what seems like a lack of peril.  Xcom can go so very badly wrong sometimes that it really makes you feel something: Tense.

Perhaps the lack of emotional connection is due to watching a Let’s Play instead of playing the game…  But usually watching Let’s Plays inspire me to want the game.  Dishonored looks a little flat, emotionally.

Nope…  It’s just me.  Dishonored has far exceeded sales expectations.  It’s headed into franchise territory.
