Even if Famitsu don't give out too many "perfect" scores they still give awfully high scores to most RPG's that make their way to the shelves.
I stopped taking them seriously when they gave Final Fantasy XIII a 39/40. I was very excited when the game got that score as I'm a huge Final Fantasy fan. To this day I got halfway through it and it's never come off my shelf ever since. It's essentially a dust collector now.
I think Tales will be a good game, though. Namco Bandai have made some killer RPG's over the years that had me addicted for months. I also hope it does raise the sales of FIVE a bit
