That's just a fault with the standard JRPG format I think. I'm playing Rogue Galaxy at the moment, and I've come to the conclusion that the JPRG genre is actually nowt more than terrible game design! They get all and sundry ideas and squeeze them in without leaving anything out, which results in far too much 'stuff' of which most is irrelevant - skills, weapons and items you never use. The end result drags on for many tens of hours not pushing forward on story or gameplay, instead relying on repetitive grind to pad out those hours. And then there's the cutscenes which, sometimes good, they can go overboard on. One night I wanted to end the game and go to bed, only to be confronted with a half hour cutscene which you don't nkow how long it is so you watch just a bit more hoping it'll end soon, and then a bit more, and then a bit more... And to add insult to injury, when the cutscene is finished and you step onto a save point (normally chaotically placed, so some areas get three in a local zone, and others have them very sparse and require you to slog through another 45 minutes of game just to find a place to stop), another cutscene starts up!
I'm a sucker for cel-shaded titles, and Rogue Galaxy does look fantastic. An HD engine would be as good as the 'real thing'. However I've found I just can't get on with JRPGs any more. 60 hour games are too much. FFXIII would have to be a major diversion from the usual style of JRPG for me to consider it.
