ToV looks a lot better graphically than ToS2. I have both games and I can see just by looking at them. Gameplay-wise, I'm not really sure as I'm not really playing them (my gf is a big tales of fan and I got them for her).
Good showing for ToV as it's clearly the 2nd best selling 360 game ever in Japan(Blue Dragon being first of course). I say clearly because after week 1 there were a few other 360 games close to it(% of error and all that stuff), but now it holds the 2nd place spot on its own. Hopefully it can manage to stay in the top 20 next week as well, or at least close to it. :)
