Gonna say either Nier or Deadly Premonition. I love both games dearly, two of my top games of last gen, but I'm under no delusions that either game is "good" by traditional standards. Sticking with them til the end wasn't challenging - they were both fun, had excellent stories, and exuded quirky charm. To be fair Nier's gameplay was simply mediocre, while Deadly Premonition was almost comically bad. Don't regret beating them. Will gladly beat them again someday.
