3PO droids were pretty common. It's quite possible that he just never imagined that of all the 3PO droids in the universe, C-3PO would end up being sold to him by Jawas 22 years later. Not being recognized by C-3PO probably didn't help.

Adding to this is the fact that C-3PO never identifies himself as such to Owen.


  OWEN: I have no need for a protocol droid.
  
  THREEPIO: (quickly) Sir -- not in an environment such as this --
  that's why I've also been programmed for over thirty secondary
  functions that...
  
  OWEN: What I really need is a droid that understands the binary
  language of moisture vaporators.
  
  THREEPIO: Vaporators! Sir -- My first job was programming binary load
  lifter...very similar to your vaporators. You could say...
  
  OWEN: Do you speak Bocce?
  
  THREEPIO: Of course I can, sir. It's like a second language for
  me...I'm as fluent in Bocce...
  
  OWEN: All right shut up! (turning to Jawa) I'll take this one.
  
  THREEPIO: Shutting up, sir.
  
  OWEN: Luke, take these two over to the garage, will you? I want you to
  have both of them cleaned up before dinner.


It is not until Luke has taken both of the droids to the garage to clean them up that either of the droids are identified by name to any of them.

(note that this version omits the line where Owen asks C-3PO if he is a protocol droid, but that is present in this version of the draft).

Why doesn't Owen Lars recognize C-3PO during ANH?
I have been playing &amp; GMing for some time, mostly in various versions of D&amp;D, and other 80s-90s systems. And most of my GMing has been with published adventure modules.

I want to try Dungeon World, so have been looking for a free adventure that would work as an introduction to the system (for both the players and myself). But most of what I can find are "Dungeon Starters":


  Dungeon Starters are a form of GM prep for running the first session of a Dungeon World game. Dungeon Starters don’t dictate plot, they’re not Fronts (you write those after the first session), and they don’t replace the GM playbook. They are for those times when you want to just sit down and start a game right then. Dungeon Starters provide a unified flavor to your prep but, when you get down to it, they are really just an unordered cloud of blanks and hooks with some appropriate moving parts to make sure the players don’t catch you with nothing interesting to say. Dungeon Starters are made up of questions, impressions, custom moves, items and services, spells, and monsters (among other things).


Are there any free adventures with a level of detail closer to a D&amp;D module?
