So Ima throw out Resonance of Fate (End of Eternity). Which is probably one of the most fascinating games to me because of the simple fact that it's not extraordinary in hardly any way, the story is pretty lackluster, and the combat system is incredibly difficult to learn with poor tutorials and an unfathomable difficulty level. Yet the design, voice acting, and overall fun gameplay has brought me back to play through this over 3 times and I have never played games fully through even twice save for games like Left 4 Dead. Something about it is just so well done that even after beating it I crave coming back to it just to see the characters again.
