For the most part, I'm the inverse of you, in that I always feel think that gameplay is king in my video games. That said, I can totally get into narrative-focused games, if they've got a great story and interesting characters. Put it this way, I don't mind if a game has amazing gameplay and a terrible story, but if the game has terrible gameplay and an amazing story, I find it much harder to slog through. I kinda feel like a great story is additive in video games imho. Interesting topic, though!
