Yeah, I think one of the game's key features is it's very well refined feel. I know that doesn't sound like much, but you know how when you play a game you can often tell if it's gone through, say, Blizzard or Valve levels of polish simply by how the game feels when you play. Things like movement, intertia, the way the animation responds, how one action flows into another, etc... It's these little details that take a lot of extra time to refine that show how much they want the game to be good.
