Re the video games, yes absolutely I've done this. I don't think I've 100% finished a game, at least not in the last 20 years. Playing through the latest Zelda game I had to pick my moment when to go take on the final boss carefully, I know that once I beat a game I'm a lot less inclined to keep going on side quests and finding shrines/korok seeds/whatever collectibles that particular game has. So I wanted to do as much of that as I could before going after Ganondorf, but I also didn't want to wait too long because if I make myself do ALL the side quests and get ALL the collectibles I'll burn and not even bother finishing the game.

That's where I'm at with RDR2. I'm forcing myself to finish everything I can before I go forward any more in the story.
