That statement really resonated with me. I'm currently playing Battlefield 3 on the Xbox and the number of times I've died because I went to duck into a doorway to avoid enemy fire, only to get halted because the door frame has a 3cm ledge that my battle hardened soldier has difficulty stepping over.

It's amazing how a seemingly trivial issue can really drive up the frustration with a game and take away from it's enjoyment.
