Shifting Random or Sifting Random?

Hey, how are ya?

So last time, i mentioned talking about Borderlands 2 with my next post.  I'm actually changing from that.  I want to talk about something always in front of my mind when it comes to games and gaming theory.  Unfortunately, i don't know a concise way to say it, though i blurted out something like it at the end of my previous post.

I'll go with "Choose vs Find".  Choose refers to the player deciding precisely the tools they use to interact with the world, and Find refers to content that you have little say over.  Indeed, Find refers to content that very few have sway over, save the developing entity taken as a whole.
