It was four minutes into Tales of Graces f that I met the amnesiac with the impossible purple pigtails. She didn't know who she was, or where she came from, or anything really. She was a deadly martial artist, but nearly walked right off a cliff. Later she asked the meaning of the word "friend." I threw up in my mouth a little and realized that Graces f would be a tale quickly forgotten. In hindsight, I guess the cover art should have served as warning.
But if the whole game boiled down to waiting for the kid in the Elvis getup to realize that the king is possessed by a demon, I wouldn't have played it for almost ninety hours. Yes, a lot of time is wasted running errands through copy-paste corridors while the characters say how they feel and explain magical jargon. But then you run into a giant spider, and the kids' anime story melts away for a few seconds of glorious battle.
I'll even say that Tales of Graces f has my favorite RPG combat, taking the crown from predecessor Tales of Symphonia. Graces f layers new abilities and limitations onto Symphonia's melee-and-magic arena skirmishes, and the end result is a more dynamic structure that makes earlier games in the series look like button mashing. It's also complicated as hell.
