I like how Bethesda gets away with releasing a game 30% done and its expected for modders to finish and fix it for them.
What other game company does this?
Infinity Ward, the don't just release an unfinished game, they release the same game every other year.
And Skyrim is finished, there are many many lines of dialogue but when you walk by the same person 400 times you are bound to hear the dialogue again.
