ELI5: Why don't video games come out when they're finished?

Fallout 4 and every other game I want makes me ask this question everytime. 

-When I mean "finished" I'm referring to the content on the game copies sent to stores and what is pre-downloaded through steam or xbox live. Not day 1 patches. The stores have the copies. The marketing for Fallout 4 or Halo 5 was well completed before these games hit the shelves. Is it common courtesy to come out on Tuesday and never any other day or is it due to some places wont be shipped the game until "launch" day so they have it fair for everyone?

It is impossible to make any software absolutely perfect.  Development is a very long process and releases are timed with an estimate on when it will be done and coordinated with marketting.
  
  Would you rather every game be delayed at the last minute because a clipboard animates like a shield?
